zero-riscy: RISC-V Core
zero-riscy* is a small 2-stage RISC-V core derived from RI5CY.
zero-riscy fully implements the RV32IMC instruction set and a minimal set of RISCV privileged specifications. zero-riscy can be configured to be very small by disabling the RV32M extensions and by activating the RV32E extensios. This configuration is called micro-riscy
The core was developed as part of the PULP platform for energy-efficient computing and is currently used as the control core for PULP and PULPino.
Documentation
A datasheet that explains the most important features of the core can be found
in the zeroriscy-doc repository.
