lowRISC News
A silicon root of trust (SiRoT) provides foundational protection for computer systems, independently of the platform operating system and application processor. OpenTitan, the world’s first open-source SiRoT, offers commercial-grade security in a transparent, verified and flexible design and is made available under a permissive license (Apache 2.0) to all who require it.
- Discrete engineering sample design taped out in August 2023, production silicon 2024
- Integrated design (for on chiplet / on SoC use) in active development, publicly released in Nov 2023
- Development boards available to purchase here
lowRISC offers Silicon Commons training and paid support services for OpenTitan and its constituent IP blocks.
Ibex is a production-quality open source 32-bit RISC-V CPU core written in SystemVerilog. The CPU core is heavily parametrizable and well suited for embedded control applications.
Ibex has been extensively verified, has seen multiple tape-outs (e.g. OpenTitan) and is used in many other projects including Microsoft’s CHERIOT-Ibex & the InnovateUK funded Sunburst Project.
lowRISC offers paid support services for Ibex.
