lowRISC is a not-for-profit company with a full stack engineering team based in Cambridge, UK. They use collaborative engineering to develop and maintain open source silicon designs and tools.

Ibex (formerly known as zero-riscy) is a small 32 bit RISC-V core. With its two-stage pipeline and support for the RV32IMC instruction set Ibex is ideally suited as control core in many embedded scenarios. Ibex is a high-quality core: together with the RTL, lowRISC provides full UVM-based verification, extensive documentation and all the tools to successfully integrate Ibex into designs. All development of Ibex is performed in the open in the lowRISC/ibex GitHub project, where we also have an issue tracker to ask questions or get feedback from our developers.
