Embodiment Construction

[0120] See figure 1 — Figure 7 , the multi-DSP and FPGA parallel processing system of the present invention includes: FPGA, DSP, AD, DA, DDR3, and power supply chip.

[0121] The present invention includes multiple FPGAs, and the functions of each FPGA are different. FPGA1 of the interface board controls two channels of AD to collect data; the collected data can be preprocessed; the preprocessed results are transmitted to FPGA4 and FPGA5 of the core board through SRIO; the processing results of FPGA4 and FPGA5 are received at the same time; SRIO is passed to DSP1 of the interface board; it receives the command of DSP1 and controls FPGA2 of the interface board according to the command. FPGA2 of the interface board controls the DA output waveform according to the command of FPGA1. The function of the FPGA3 of the core board is to control the power-on sequence of the core boards DSP2 and DSP3. The functions of FPGA4 and FPGA5 of the core board are similar, and they cooperate...

Description

technical field [0001] The invention relates to a multi-DSP and FPGA parallel processing system and an implementation method. It is based on high-speed serial protocols such as PCIe, SRIO and Hyperlink, and realizes high-speed serial interconnection in the multi-DSP and FPGA parallel processing system, which belongs to digital signal processing. field. Background technique [0002] High-speed serial interface generally refers to the serial interface using differential technology and clock embedded technology. Unlike low-speed serial interfaces such as SPI, the transfer rate of high-speed serial interfaces can reach several Gbps. The high-speed serial interface uses differential signal lines instead of single-ended signal lines, thereby enhancing anti-interference and anti-noise capabilities. Compared to parallel interfaces, serial interfaces require fewer pins, thereby increasing the number of ports that can be integrated and simplifying PCB traces, cables, and connector s...
