Embodiment Construction
[0027] The development board designed by the present invention has two innovative points: one is that the imitation storage bandwidth is much larger than other multi-FPGA development boards, and the other is that the inter-chip communication throughput rate is super large.
[0028] like figure 1 , there are 4 Xilinx XC6VLX550T chips (FF1759) on the motherboard of the present invention, and high-speed GTX input and output interfaces and common I / O are used to realize full interconnection between the chips, so as to realize the pipeline parallelism of NoC multi-core processor processing data. The name of the serial transceiver is different, the V4 period is called MGT, the early V5LXT / SXT is GTP, and the later V5FXT is called GTX. For the future versatility of the FPGA mainboard, the present invention adopts a fully interconnected structure, and each FPGA chip is provided with three large groups of GTX IO interfaces that are respectively connected to the corresponding GTX IO int...
