Description of the Invention: [Technical Field of the Invention] The present invention relates to an embedded system and an access method thereof, and more particularly to an embedded material of an external memory module and a method for accessing the same. &Under the [previous technology] At present, with the rapid development of network communication technology, various embedded systems have gradually become the main tools for people to access data such as mobile phones, printers, air conditioners, and images. The sensor is equal to 岣^. A case system. Since the image sensor needs to perform a series of parameter measurement before use, for example, the signal_to-noise ratio (SNR), the image degree, the dark current of the pixel, etc., if tested by a computerized detection system, The linear product is large, and the user's operation is complicated. Therefore, the embedded system with small size and design process can be replaced by the body. Therefore, the use of sensor parameter detection often requires a large amount of memory space. However, the image and image data, for example, the image sensor signal noise is calculated, and the image data is repeatedly captured into the memory space during storage, so that the embedded body capacity may be insufficient, and the memory management or system is used in the past. Memory space as a solution. Among them, memory management is: the technology of reconciliation, the allocation and use of physical resources, and its main purpose is to allocate computer memory, and release and reclaim memory at an appropriate time, which is efficient and fast. The embedded system is embedded in the original embedded system, and the embedded memory module with increased system memory is replaced. Control Μ : Module, which stores the data 铋 leaves in the memory module 201128523 by another large capacity, t剌 module, so that the data will be stored in the traditional method of “multi-time”. =, after reading the bedding leaf p, grab the required discretion, which will increase the calculation time. ® /r is the Beco' [invention] In view of the above-mentioned conventional techniques The system and its access to the data system are not enough memory (4). 乂 Solve the embedded ## one of the inventions, propose an embedded system, in which the module package and a memory module, and the memory The medium-and-external memory module can be a flash memory or an external hard disk. According to one of the objects of the present invention, the memory is stored and stored in a 1_L sub-intrusion system and stored and The method of reading data, the control module will at least = hexadecimal conversion; go, store in the memory module, "^ turn ^ method is hexadecimal conversion method; control module will at least - data to ^ ^ The conversion method 'reading the binary conversion method from the memory module towel is a binary conversion method. A plurality of incorporations according to the present invention may have - or (the embedded system can be insufficiently memoryd by an external memory module embedded system itself.
