本說明書實施例提供一種資訊識別方法、伺服器、客戶端及系統。
為了使本技術領域的人員更好地理解本說明書中的技術方案，下面將結合本說明書實施例中的圖式，對本說明書實施例中的技術方案進行清楚、完整地描述，顯然，所描述的實施例僅僅是本說明書一部分實施例，而不是全部的實施例。基於本說明書中的實施例，本領域普通技術人員在沒有做出創造性勞動前提下所獲得的所有其他實施例，都應當屬於本說明書保護的範圍。
目前，在一個場景中，公共自行車利用車樁進行存放，一輛公共自行車可以對應一個自行車樁，每個車樁上通常顯示有二維條碼，用戶租用公共自行車時，通常利用客戶端掃描該公共自行車對應的車樁上的二維條碼，客戶端執行演算法對該二維條碼進行解碼可以獲取該二維條碼的碼值，利用該二維條碼的碼值可以與伺服器進行資料通信實現自行車的租用或退還操作。但是日曬導致圖片褪色、人為破壞等原因導致車樁上的二維條碼破損或有污漬時，客戶端可能無法識別被污損的二維條碼，進而導致用戶不能租車或還車。在另一個場景中，用戶可以通過掃描商家提供的公眾號二維條碼可以關注商家的公眾號，進而可以參與商家公眾號中提供的相關活動，但當該二維條碼上有污點時，用戶通過掃描該二維條碼無法實現對商家公眾號的關注，導致不能參加商家公眾號中的相關活動。基於此，本說明書實施例中可以在用戶客戶端無法識別二維條碼等條碼時，通過伺服器中儲存的條碼圖片的圖片與該條碼的圖片的比對，篩選出該條碼未被污損時的條碼圖片，通過識別該未被污損時的條碼圖片，得到該條碼的碼值，從而提高資訊識別的成功率。
以下介紹本說明書一種資訊識別方法的一種具體實施例。圖1是本說明書提供的資訊識別方法的一種實施例的流程示意圖，本說明書提供了如實施例或流程圖所述的方法操作步驟，但基於常規或者無創造性的勞動可以包括更多或者更少的操作步驟。實施例中列舉的步驟順序僅僅為眾多步驟執行順序中的一種方式，不代表唯一的執行順序。在實際中的系統或設備產品執行時，可以按照實施例或者圖式所示的方法順序執行或者並行執行(例如並行處理器或者多線程處理的環境)。具體的如圖1所示，該方法可以包括以下步驟。
S102：掃碼客戶端獲取待識別條碼圖片，識別該待識別條碼圖片對應的碼值，若識別失敗，向伺服器發送解碼請求。該解碼請求包括：該待識別條碼圖片。
掃碼客戶端可以獲取待識別條碼圖片，該待識別條碼圖片中包含第二條碼。識別該待識別條碼圖片中第二條碼的目標碼值。該條碼可以是條形碼、二維條碼等。
若掃碼客戶端識別該待識別條碼圖片失敗，則可以向該伺服器發送解碼請求。該解碼請求中可以包括該待識別條碼圖片。
圖2是本說明書提供的實施例中待識別條碼圖片的一個示意圖。若掃碼客戶端不能識別出圖2所示的二維條碼的碼值，那麼，掃碼客戶端可以向該伺服器發送識別圖2所示二維條碼的請求，該請求中可以包含圖2所示的二維條碼。
在另一實施方式中，該掃碼客戶端還可以向該伺服器發送該待識別條碼圖片對應的身份資訊。
S104：該伺服器接收該解碼請求，從該伺服器儲存的條碼圖片中篩選出與該待識別條碼圖片匹配的目標條碼圖片。
該伺服器可以預先儲存條碼圖片。該伺服器儲存的條碼圖片可以是可識別的條碼圖片。該伺服器可以將該第一條碼圖片儲存在指定位置。該指定位置可以是記憶體中用於儲存所有條碼圖片的位置。
在一個實施方式中，該伺服器儲存的條碼圖片可以是由搜集客戶端發來的。具體地，搜集客戶端可以獲取第一條碼圖片，該搜集客戶端可以通過執行解碼演算法識別該第一條碼圖片對應的碼值，若該搜集客戶端識別出第一條碼圖片對應的第一碼值，可以將該第一條碼圖片發送給該伺服器。伺服器可以接收並儲存該第一條碼圖片。
在另一個實施方式中，該搜集客戶端還可以將與該第一條碼圖片對應的第一碼值發送給該伺服器。那麼，該伺服器還可以儲存與該第一條碼圖片對應的第一碼值。
圖3是本說明書提供的實施例中的一個第一條碼圖片的示意圖。利用解碼演算法，搜集客戶端可以識別出圖3所示的二維條碼對應的碼值為“你好”。那麼，該搜集客戶端可以將圖3所示的二維條碼圖片發送給伺服器。伺服器可以儲存該二維條碼圖片。進一步地，該搜集伺服器還可以將圖3所示的二維條碼對應的碼值“你好”發送給伺服器。伺服器可以儲存該碼值“你好”。
在另一個實施方式中，該伺服器儲存的條碼圖片可以是由條碼對應的商家客戶端發來的。具體地，商家客戶端生成第一條碼圖片後，可以將該第一條碼圖片發送給該伺服器。該伺服器可以接收並儲存商家客戶端發出的第一條碼圖片。進一步地，該商家客戶端還可以將與該第一條碼圖片對應的第一碼值發送給該伺服器。那麼，該伺服器還可以儲存與該第一條碼圖片對應的第一碼值。
在一個實施方式中，該伺服器還可以預先儲存與條碼圖片對應的身份資訊。該身份資訊可以包括：地址資訊和/或名稱資訊。具體地，可以是條碼圖片中條碼所在的地址資訊和/或該條碼圖片中條碼對應對象的名稱等。例如，在一個應用場景中，若第一條碼圖片中的條碼為公共自行車車樁上的二維條碼，那麼，該第一條碼圖片的身份資訊可以是該公共自行車車樁所在的位置資訊。在另一應用場景中，若第一條碼圖片中的條碼為商家的公眾號二維條碼，那麼，該第一條碼圖片的身份資訊可以是商家的名稱和/或該商家的地址資訊。
進一步地，該伺服器預先儲存的圖片可以包括：該分期根據該身份資訊儲存的條碼圖片。具體地，可以包括：該伺服器按照該身份資訊分配儲存地址的條碼圖片。在一個應用場景中，一個公共自行車租賃點可能具有多個公共自行車車樁，一個車樁可以具有一個二維條碼。由於該租賃點處多個車樁對應的地址資訊相同，那麼，該租賃點處多個二維條碼可以對應相同的身份資訊，這些身份資訊相同的二維條碼圖片可以儲存在相同的位置。通過利用該身份資訊為該儲存的條碼圖片分配儲存位置，可以使得對應的對象名稱相同或相近、地址資訊相同或相近的條碼圖片儲存在同一位置，方便對儲存的資料進行管理和查找。
該伺服器可以接收該掃碼客戶端發出的解碼請求。該伺服器可以獲取該解碼請求中的待識別條碼圖片。該伺服器可以從該伺服器儲存的條碼圖片中篩選出與該待識別條碼圖片匹配的目標條碼圖片。
該從該伺服器儲存的條碼圖片中篩選出與待識別條碼圖片匹配的目標條碼圖片可以包括：計算該伺服器儲存的條碼圖片與該待識別條碼圖片的相似度，篩選出相似度最高的條碼圖片作為目標條碼圖片。
在一個實施方式中，該伺服器還可以接收該掃碼客戶端發出的與該待識別條碼圖片對應的身份資訊。進一步地，該伺服器可以根據該待識別條碼圖片對應的身份資訊，確定候選條碼圖片，從該候選條碼圖片中篩選出與該待識別條碼圖片匹配的目標條碼圖片。
其中，該伺服器可以根據該待識別條碼圖片對應的身份資訊，確定候選條碼圖片可以包括：可以將身份資訊與待識別條碼圖片的身份資訊相同的條碼圖片作為該候選條碼圖片。
在一個應用場景中，地址資訊相同的多個二維條碼圖片可能被儲存在伺服器的相同位置，例如，伺服器的儲存位置“位置1”處儲存的20個自行車車樁上的二維條碼對應的地址資訊都為“北京市人民路1號”，那麼，當掃碼客戶端請求解碼的二維條碼為圖2所示的二維條碼，該二維條碼對應的身份資訊為“北京市人民路1號”時，可以將儲存位置“位置1”處儲存的20個自行車車樁上的二維條碼作為候選條碼圖片。伺服器可以從該20個候選條碼圖片中篩選出與待識別條碼圖片相似度最高的條碼圖片(例如，圖3所示的二維條碼圖片)作為目標條碼圖片。
通過利用身份資訊，可以對儲存的條碼圖片進行初步的篩選，從初步篩選的結果中進一步進行相似度計算，可以減少計算量，提高條碼圖片的匹配效率。

S108：該掃碼客戶端接收該目標條碼圖片，識別該目標條碼圖片對應的目標碼值，將該目標碼值作為該待識別條碼圖片對應的碼值。
在一個實施方式中，該掃碼客戶端可以接收該目標條碼圖片，識別該目標條碼圖片對應的目標碼值，並將該識別出的目標碼值作為該待識別條碼圖片對應的碼值。
例如，若掃碼客戶端向伺服器發送的不能識別的待識別條碼圖片為圖2所示的二維條碼圖片，伺服器反饋給掃碼客戶端的目標條碼圖片為圖3所示的二維條碼圖片，那麼掃碼客戶端可以識別出該二維條碼對應的碼值為“你好”，並將碼值“你好”作為圖2所示的二維條碼的碼值。
需要說明的是，在本說明書提供的實施方式中，該掃碼客戶端與該搜集客戶端可以是相同的客戶端，也可以是不同的客戶端。例如，在一個應用場景中，一個客戶端識別一個二維條碼，若識別成功，可以將該二維條碼發送給伺服器，此時，可以將該客戶端稱為搜集客戶端；若該客戶端識別一個二維條碼時識別失敗，可以向伺服器發送解碼請求，此時，可以將該客戶端稱為掃碼客戶端。

在20世紀90年代，對於一個技術的改進可以很明顯地區分是硬體上的改進(例如，對二極體、電晶體、開關等電路結構的改進)還是軟體上的改進(對於方法流程的改進)。然而，隨著技術的發展，當今的很多方法流程的改進已經可以視為硬體電路結構的直接改進。設計人員幾乎都通過將改進的方法流程編程到硬體電路中來得到相應的硬體電路結構。因此，不能說一個方法流程的改進就不能用硬體實體模組來實現。例如，可程式化邏輯元件(Programmable Logic Device，PLD)(例如現場可程式化閘陣列(Field Programmable Gate Array，FPGA))就是這樣一種積體電路，其邏輯功能由用戶對元件編程來確定。由設計人員自行編程來把一個數位系統“集成”在一片PLD上，而不需要請晶片製造廠商來設計和製作專用的積體電路晶片。而且，如今，取代手工地製作積體電路晶片，這種編程也多半改用“邏輯編譯器(logic compiler)”軟體來實現，它與程式開發撰寫時所用的軟體編譯器相類似，而要編譯之前的原始代碼也得用特定的編程語言來撰寫，此稱之為硬體描述語言(Hardware Description Language，HDL)，而HDL也並非僅有一種，而是有許多種，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)與Verilog。本領域技術人員也應該清楚，只需要將方法流程用上述幾種硬體描述語言稍作邏輯編程並編程到積體電路中，就可以很容易得到實現該邏輯方法流程的硬體電路。
控制器可以按任何適當的方式實現，例如，控制器可以採取例如微處理器或處理器以及儲存可由該(微)處理器執行的電腦可讀程式代碼(例如軟體或韌體)的電腦可讀介質、邏輯閘、開關、專用積體電路(Application Specific Integrated Circuit，ASIC)、可程式化邏輯控制器和嵌入微控制器的形式，控制器的例子包括但不限於以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20 以及Silicone Labs C8051F320，記憶體控制器還可以被實現為記憶體的控制邏輯的一部分。本領域技術人員也知道，除了以純電腦可讀程式代碼方式實現控制器以外，完全可以通過將方法步驟進行邏輯編程來使得控制器以邏輯閘、開關、專用積體電路、可程式化邏輯控制器和嵌入微控制器等的形式來實現相同功能。因此這種控制器可以被認為是一種硬體部件，而對其內包括的用於實現各種功能的裝置也可以視為硬體部件內的結構。或者甚至，可以將用於實現各種功能的裝置視為既可以是實現方法的軟體模組又可以是硬體部件內的結構。
上述實施例闡明的裝置、模組或單元，具體可以由電腦晶片或實體實現，或者由具有某種功能的產品來實現。一種典型的實現設備為電腦。具體的，電腦例如可以為個人電腦、筆記型電腦、蜂巢式電話、相機電話、智慧型電話、個人數位助理、媒體播放器、導航設備、電子郵件設備、遊戲控制台、平板電腦、可穿戴設備或者這些設備中的任何設備的組合。

In order to enable those skilled in the art to better understand the technical solutions in this specification, the following will clearly and completely describe the technical solutions in the embodiments of this specification in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only a part of the embodiments in this specification, rather than all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art without creative work should fall within the protection scope of this specification.
At present, in a scene, public bicycles are stored in piles. One common bicycle can correspond to one bicycle pile. Each pile usually displays a two-dimensional bar code. When a user rents a public bicycle, he usually uses the client to scan the public bicycle. The two-dimensional bar code on the pile corresponding to the bicycle, the client executes an algorithm to decode the two-dimensional bar code to obtain the code value of the two-dimensional bar code, and the code value of the two-dimensional bar code can be used to communicate with the server to realize the bicycle Lease or refund operation. However, when the 2D barcode on the car pile is damaged or stained due to the fading of the picture due to sunlight, man-made damage, etc., the client may not be able to recognize the stained 2D barcode, and the user may not be able to rent or return the car. In another scenario, the user can follow the official account of the merchant by scanning the QR code of the official account provided by the merchant, and then can participate in the related activities provided in the official account of the merchant, but when the QR code is stained, the user can pass Scanning the two-dimensional bar code fails to pay attention to the merchant's official account, resulting in the inability to participate in related activities in the merchant's official account. Based on this, in the embodiments of this specification, when the user client cannot recognize a barcode such as a two-dimensional barcode, the image of the barcode image stored in the server can be compared with the image of the barcode to filter out when the barcode is not defaced. By identifying the bar code picture when it is not defaced, the code value of the bar code is obtained, thereby improving the success rate of information recognition.
The following describes a specific embodiment of an information recognition method in this specification. Figure 1 is a schematic flow diagram of an embodiment of the information recognition method provided in this specification. This specification provides the method operation steps as described in the embodiment or flowchart, but based on conventional or uninvented labor may include more or less Steps. The sequence of steps listed in the embodiment is only one way of the execution sequence of many steps, and does not represent the only execution sequence. When the actual system or device product is executed, it may be executed sequentially or in parallel according to the method shown in the embodiment or the drawings (for example, a parallel processor or a multi-threaded processing environment). Specifically, as shown in FIG. 1, the method may include the following steps.
S102: The scan code client obtains the barcode image to be identified, identifies the code value corresponding to the barcode image to be identified, and if the identification fails, sends a decoding request to the server. The decoding request includes: the barcode image to be identified.
The scan code client can obtain the barcode image to be identified, and the barcode image to be identified contains the second barcode. Identify the target code value of the second bar code in the bar code picture to be identified. The barcode can be a barcode, a two-dimensional barcode, and so on.
If the scanning client fails to recognize the barcode image to be recognized, it can send a decoding request to the server. The decoding request may include the barcode image to be identified.
Figure 2 is a schematic diagram of a bar code image to be identified in the embodiment provided in this specification. If the scanning client cannot identify the code value of the two-dimensional barcode shown in Figure 2, then the scanning client can send a request to the server to identify the two-dimensional barcode shown in Figure 2, and the request can include Figure 2 The two-dimensional bar code shown.
In another embodiment, the scan code client can also send the identity information corresponding to the barcode image to be identified to the server.
S104: The server receives the decoding request, and selects a target barcode image matching the barcode image to be identified from the barcode images stored in the server.
The server can store barcode images in advance. The barcode image stored by the server may be a recognizable barcode image. The server can store the first barcode image in a designated location. The designated location can be a location in the memory for storing all barcode images.
In one embodiment, the barcode image stored by the server may be sent by the collection client. Specifically, the collection client can obtain the first barcode image, and the collection client can identify the code value corresponding to the first barcode image by executing a decoding algorithm. If the collection client recognizes the first code corresponding to the first barcode image Value, the first barcode image can be sent to the server. The server can receive and store the first barcode image.
In another embodiment, the collection client may also send the first code value corresponding to the first barcode picture to the server. Then, the server may also store the first code value corresponding to the first barcode picture.
Fig. 3 is a schematic diagram of a first bar code picture in the embodiment provided in this specification. Using the decoding algorithm, the collection client can recognize that the code value corresponding to the two-dimensional barcode shown in Figure 3 is "Hello". Then, the collection client can send the two-dimensional barcode picture shown in FIG. 3 to the server. The server can store the two-dimensional barcode image. Further, the collection server may also send the code value "Hello" corresponding to the two-dimensional barcode shown in FIG. 3 to the server. The server can store the code value "Hello".
In another embodiment, the barcode image stored by the server may be sent by the merchant client corresponding to the barcode. Specifically, after the merchant client generates the first barcode image, the first barcode image may be sent to the server. The server can receive and store the first barcode image sent by the merchant client. Further, the merchant client can also send the first code value corresponding to the first barcode picture to the server. Then, the server may also store the first code value corresponding to the first barcode picture.
In one embodiment, the server may also pre-store the identity information corresponding to the barcode image. The identity information may include: address information and/or name information. Specifically, it may be the address information of the barcode in the barcode picture and/or the name of the object corresponding to the barcode in the barcode picture, etc. For example, in an application scenario, if the barcode in the first barcode picture is a two-dimensional barcode on a public bicycle pile, then the identity information of the first barcode picture may be the location information of the public bicycle pile. In another application scenario, if the barcode in the first barcode image is a two-dimensional barcode of the merchant's official account, then the identity information of the first barcode image may be the name of the merchant and/or the address information of the merchant.
Further, the image pre-stored by the server may include: the barcode image stored in the installment according to the identity information. Specifically, it may include: the server allocates a barcode image of a storage address according to the identity information. In an application scenario, a public bicycle rental point may have multiple public bicycle piles, and one pile may have a two-dimensional barcode. Since the address information corresponding to the multiple truck stakes at the rental point is the same, the multiple two-dimensional barcodes at the rental point can correspond to the same identity information, and the two-dimensional barcode images with the same identity information can be stored in the same location. By using the identity information to allocate storage locations for the stored barcode images, corresponding barcode images with the same or similar object names and the same or similar address information can be stored in the same location, which facilitates the management and search of the stored data.
The server can receive the decoding request sent by the scan code client. The server can obtain the barcode image to be identified in the decoding request. The server can filter out the target barcode image that matches the barcode image to be identified from the barcode images stored in the server.
The screening of the target barcode image that matches the barcode image to be identified from the barcode images stored in the server may include: calculating the similarity between the barcode image stored in the server and the barcode image to be identified, and selecting the barcode with the highest similarity The picture is used as the target barcode picture.
In one embodiment, the server may also receive the identity information corresponding to the barcode image to be identified from the barcode scanning client. Further, the server may determine the candidate barcode image according to the identity information corresponding to the barcode image to be identified, and filter out the target barcode image matching the barcode image to be identified from the candidate barcode images.
Wherein, the server may determine the candidate barcode picture according to the identity information corresponding to the barcode picture to be recognized, which may include: a barcode picture whose identity information is the same as the identity information of the barcode picture to be recognized may be used as the candidate barcode picture.
In an application scenario, multiple two-dimensional barcode images with the same address information may be stored in the same location on the server, for example, the two-dimensional barcode on 20 bicycle stakes stored in the storage location "location 1" of the server The corresponding address information is "Beijing Renmin Road No. 1", then, when the scanning client requests to decode the two-dimensional barcode as shown in Figure 2, the corresponding identity information of the two-dimensional barcode is "Beijing "Renmin Road No. 1", the two-dimensional barcodes on the 20 bicycle piles stored in the storage location "Position 1" can be used as candidate barcode pictures. The server can select the barcode image with the highest similarity to the barcode image to be recognized from the 20 candidate barcode images (for example, the two-dimensional barcode image shown in FIG. 3) as the target barcode image.
By using the identity information, the stored barcode images can be preliminarily screened, and the similarity calculation can be further performed from the preliminary screening results, which can reduce the amount of calculation and improve the matching efficiency of the barcode images.
S106: The server sends the target barcode image to the scan code client.
The server may send the target barcode image to the scan code client.
S108: The scan code client receives the target barcode picture, recognizes the target code value corresponding to the target barcode picture, and uses the target code value as the code value corresponding to the barcode picture to be recognized.
In one embodiment, the scan code client may receive the target barcode image, identify the target code value corresponding to the target barcode image, and use the identified target code value as the code value corresponding to the barcode image to be identified.
For example, if the unrecognized barcode image sent by the scanning client to the server is the two-dimensional barcode image shown in Figure 2, the target barcode image that the server feeds back to the scanning client is the two-dimensional barcode shown in Figure 3. Picture, the scanning client can recognize that the corresponding code value of the two-dimensional bar code is "Hello", and use the code value "Hello" as the code value of the two-dimensional bar code shown in Figure 2.
It should be noted that, in the implementation manner provided in this specification, the scan code client and the collection client may be the same client or different clients. For example, in an application scenario, a client recognizes a two-dimensional barcode. If the recognition is successful, the two-dimensional barcode can be sent to the server. In this case, the client can be called a collection client; if the client When recognizing a two-dimensional barcode, the recognition fails, and a decoding request can be sent to the server. In this case, the client can be called a scan code client.

The foregoing describes specific embodiments of this specification. Other embodiments are within the scope of the attached patent application. In some cases, the actions or steps described in the scope of the patent application may be performed in a different order than in the embodiments and still achieve desired results. In addition, the processes depicted in the drawings do not necessarily require the specific order or sequential order shown in order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
In the 1990s, the improvement of a technology can be clearly distinguished from the improvement of the hardware (for example, the improvement of the circuit structure of diodes, transistors, switches, etc.) or the improvement of the software (for the process of the method). Improve). However, with the development of technology, the improvement of many methods and processes of today can be regarded as a direct improvement of the hardware circuit structure. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be realized by the hardware entity module. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is such an integrated circuit whose logic function is determined by the user's programming of the component. It is programmed by the designer to "integrate" a digital system on a PLD without requiring the chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly realized by using "logic compiler" software, which is similar to the software compiler used in program development and writing, but requires compilation. The original code before has to be written in a specific programming language, which is called Hardware Description Language (HDL), and HDL is not only one, but there are many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., currently the most Commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be clear to those skilled in the art that only a little logic programming of the method flow in the above hardware description languages and programming into the integrated circuit can easily obtain the hardware circuit that implements the logic method flow.

For example, the controller can be a microprocessor or a processor and a computer readable program code (such as software or firmware) that can be executed by the (micro) processor. Medium, logic gates, switches, application specific integrated circuits (Application Specific Integrated Circuit, ASIC), programmable logic controllers and the form of embedded microcontrollers. Examples of controllers include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicon Labs C8051F320, the memory controller can also be implemented as part of the memory control logic. Those skilled in the art also know that, in addition to implementing the controller in a purely computer-readable program code manner, it is entirely possible to program the method steps to make the controller use logic gates, switches, dedicated integrated circuits, and programmable logic controllers. And the form of embedded microcontroller etc. realizes the same function. Therefore, such a controller can be regarded as a hardware component, and the devices included in it for realizing various functions can also be regarded as a structure within the hardware component. Or even, the device for realizing various functions can be regarded as both a software module for realizing the method and a structure within a hardware component.
