PicoRV32 is a CPU core that implements the RISC-V RV32IMC Instruction Set. It can be configured as RV32E, RV32I, RV32IC, RV32IM, or RV32IMC core, and optionally contains a built-in interrupt controller. Tools (gcc, binutils, etc..) can be obtained via the RISC-V Website. The examples bundled with PicoRV32 expect various RV32 toolchains to be installed in /opt/riscv32i[m][c]. See the build instructions below for details.
