The invention can realize the perception of functions without increasing hardware resources, namely the invention can obtain the general sense integrated device based on partial reconfiguration by adapting the existing module of millimeter wave communication perception integrated signals to the FPGA and designing the perception function related module as a reconfigurable area, so that the perception function related module can dynamically change the functions and/or algorithms of the reconfigurable area according to requirements. The present invention may also load video and image processing capabilities, supporting communication, perception, and vision-integrated processing capabilities, for example.
In this embodiment, the sensing function module 03 can process the second communication transmission signal sent by the baseband interface module 01 or the second communication receiving signal sent by the device, and receive and send the processed signal, that is, the sensing function module 03 can send the second communication transmission signal from the baseband interface module 01 or receive the second communication receiving signal from the input module 04. The baseband interface module 01 may illustratively receive the second communication transmission signal after the external baseband unit receives the relevant communication signal, and then transmit the second communication transmission signal to the sensing function module 03, and the sensing function module 03 may parse the second communication transmission signal to obtain a processed second communication transmission signal, and transmit the processed second communication transmission signal to the device through the output module 05. In addition, after the input module 04 receives the related second communication receiving signal, the input module 04 may send the second communication receiving signal to the sensing function module 03, the sensing function module 03 processes the second communication receiving signal to obtain a processed second communication receiving signal, and sends the processed second communication receiving signal to the baseband interface module 01, and the baseband interface module 01 sends the processed second communication receiving signal.
It can be understood that the sensing function module 03 receives configuration information and data information from the baseband interface module 01, where the received data information from the baseband interface module 01 is the second communication sending signal, and the configuration information includes relevant information for configuring the second communication sending signal, the second communication receiving signal, and the processed second communication receiving signal. The sensing function module 03 analyzes the received second communication transmission signal, processes the second communication transmission signal to obtain a time domain digital domain signal (corresponding to the processed second communication transmission signal), and then sends the signal to the output module 05 for subsequent processing at the device end. The sensing function module 03 may illustratively perform processing on the second communication transmission signal to be transmitted, where the sensing function module 03 may perform operations such as sensing signal generation and up-conversion, or perform operations such as baseband signal generation, resource mapping, I FFT, and CP addition, on the sensing signal, or directly generate a corresponding time domain signal through a baseband interface, and the sensing function module 03 directly and transparently transmits the second communication transmission signal to the output module 05. In addition, for the second communication receiving signal of the input module 04, the sensing function module 03 may perform receiving processing to obtain a frequency domain digital domain signal or an intermediate parameter or a detection result, and send the processed second communication receiving signal to the baseband interface module 01 for subsequent processing. Illustratively, the sensing function 03 may perform operations such as CP removal, FFT extraction, sensing signal extraction, decorrelation, etc. on the sensing signal, or directly perform a decorrelation operation on the sensing signal and calculate a multidimensional FFT spectrum, such as a calculated delay spectrum, an angle spectrum, a velocity spectrum, or perform incoherent or coherent combination, angle estimation, target value output, etc. on the sensing signal.
The method comprises the steps of receiving and processing a second communication sending signal sent by the baseband interface module 01 or a second communication receiving signal sent by the equipment, analyzing to obtain a functional signal according to the second communication sending signal or the second communication receiving signal, calling a corresponding function execution file according to configuration information sent by the baseband interface module 01, and processing the functional signal through the function execution file, wherein the method comprises the following specific steps:
The method comprises the steps of receiving a second communication sending signal sent by a baseband interface module 01 or a second communication receiving signal sent by equipment, receiving first configuration information sent by the baseband interface module 01, analyzing and obtaining a function conversion instruction according to the first configuration information, and calling a function execution file for the second communication sending signal or the second communication receiving signal from a memory according to the function conversion instruction, wherein the sensing function module 03 comprises a memory, and the memory is pre-stored with the function execution files corresponding to different function conversion instructions.
Preferably, after receiving the second communication transmission signal transmitted by the baseband interface module 01 or the second communication reception signal transmitted by the device, the method further includes:
The method comprises the steps of receiving second configuration information sent by a baseband interface module 01, analyzing the second configuration information to obtain a function updating instruction, calling a data channel of a function execution file corresponding to the function updating instruction according to the function updating instruction so as to update the function execution file through the data channel, wherein each function execution file corresponds to one function updating instruction.
In this embodiment, the sensing function module 03 mainly has two functions, namely, switching of sensing functions and updating of function areas, wherein different functions in the sensing function module 03 coexist in a time-sharing manner, and specifically, different function execution files are called to execute so as to realize the time-sharing coexistence of functions. The external memory is divided into a plurality of functional areas, and both switching and updating of functions are read-write operations for the plurality of functional areas of the memory. For example, referring to fig. 5, the command format 16 bits issued by the function load and reconfiguration, the lower 2 bits represent the function selection, the highest bit is the function switch, wherein "0" is the function selection and "1" is the function update. The function switching flow is to convert the instruction into a memory function area to be operated after receiving the function switching instruction, and then read the executable file of the function area and load the executable file into the perception module function area. The flow of function update is to receive a function update instruction and update the data of the data channel to the corresponding function area in the memory. Wherein, the reserved 13 bits have no specific effect in the scheme and do not influence the function selection.
Further, the executable file for updating in the data channel may first send an interface message update instruction by the application program, and then perform the function update, for example, by receiving an M-Plane update instruction sent by the application program. After the executable file for updating arrives, the perception function module 03 updates the flash function area, wherein the M-Plane instruction is one of configuration information.
It can be understood that the general sense integrated system merges partial reconfiguration technology, does not need to switch corresponding functional modules in a reset state, can realize various different algorithm functions with smaller resources, meanwhile, the flexibility of the embodiment is high, different sensing algorithms can be stored in different functional areas, can be modified at will, occupies low logic resources, does not need to realize various sensing algorithms in the system at the same time, and can reduce power consumption and device cost.

Correspondingly, taking a positioning function module as an example, three signal transmission links also exist, wherein the first signal is sent from the analog-to-digital conversion module, sent to the baseband interface module 01 after passing through the positioning function module and then sent out, the second signal is received from an external baseband unit, so that after the signal is received by the baseband interface module 01, the signal is output to equipment through the digital-to-analog conversion module through the positioning function module, and the third signal is generated from the positioning function module and directly sent to the equipment through the digital-to-analog conversion module.
In this embodiment, after the input module 04 sends the second communication receiving signal to the sensing function module 03, if the sensing function is loaded, the second communication receiving signal is the sensing receiving signal, and further, the corresponding sensing function executing file can be called through the configuration file sent by the baseband interface module 01, so as to process the sensing receiving signal, and send the processed sensing receiving signal to the baseband interface module 01 to realize the outgoing.
Further, after the input module 04 sends the second communication receiving signal to the sensing function module 03, if the second communication receiving signal is a positioning receiving signal, and further, the corresponding positioning function executing file can be called through the configuration file sent by the baseband interface module 01, so as to process the positioning receiving signal, and further, the processed positioning receiving signal is sent to the baseband interface module 01 to realize the sending out.
