Fuxi SoC

Fuxi SoC is a simple system-on-chip based on Fuxi processor. This design can be synthesised and implemented on development board with Xilinx 7 Series FPGA.

Fuxi SoC has already been tested on Loongson FPGA development board (with Xilinx XC7A200TFBG676-2).

Requirement

• Xilinx Vivado 2018.3.
• Xilinx FPGA.
