Tang Nano 9K Simple PicoRV32-based SoC on FPGA

This video shows how to create a very simple system-on-a-chip (SoC) using the PicoRV32 RISC-V core and the Tang Nano 9K FPGA development board. The goal is a simple and consistent design that is not abstracted but is easy to extend. We show both Verilog for the SoC and C code for software on the PicoRV32 soft core.
