-The SiFive E20 Standard Core is an extremely efficient implementation of the E2 Series configured for very low area and power. The E20 brings the power of the RISC-V software ecosystem to efficiently address traditional 8-bit and 32-bit microcontroller applications such as IoT, Analog Mixed Signal, and Programmable Finite State Machines.
-
-This core target is suitable with Verilog RTL for verification and running application software building on top of freedom-metal libraries. The target supports:
-
-- 1 hart with RV32IMC core
-- 4 hardware breakpoints
