3種不同的Bus bridge 連接HPS (ARM SoC)和 FPGA

FPGA Fabric 內部元件連接使用的是Avalon Bus, 而ARM SoC 內部使用 AXI Interface.

Intel  SoC FPGA 解決方案使用可以使用3種不同的bridge 連接HPS (ARM SoC)和 FPGA

1. HPS-to-FPGA Bridge : HPS ---> FPGA (for high perfromancee data transfer)
2. Lightweight HPS-to-FPGA Bridge: HPS ---> FPGA (for low perfromancee , fixed 32bit data width,tune for latency. suitable for control and status register access)
3. FPGA-to-HPS Bridge: FPGA---> HPS
