Ibex: RISC-V Core

Ibex is a small 32 bit RISC-V core with a 2-stage pipeline.

Ibex fully implements the RV32IMC instruction set and a small set of RISC-V privileged specifications. Ibex can be configured to be very small by disabling the RV32M extensions and by activating the RV32E extensions.

This core was initially developed as part of the PULP platform under the name "Zero-riscy", and has been contributed to lowRISC who maintains it and develops it further.

Ibex is under active development, with further code cleanups, feature additions, and test and verification planned for the future.
