Creating a fully open-source SoC design

lowRISC is a not-for-profit project to produce a completely open source SoC (System on Chip), with plans for volume silicon manufacture and low-cost development boards. We use the open RISC-V instruction set architecture, and are based at the University of Cambridge Computer Laboratory. lowRISC has its roots in the Raspberry Pi project, which two of the co-founders were heavily involved in.

The ultimate goals of lowRISC are:

  • To create a fully open SoC and low-cost development board and to support the open-source hardware community. This will involve volume silicon manufacture.
  • To explore and promote novel hardware security features
  • To make it simple for existing companies and especially semiconductor startups to create derivative designs, e.g. by sharing scripts, tools, source and our experience
  • To create a benchmark design to aid academic research

We are taking part in GSoC as an umbrella project, in collaboration with a number of other projects, either directly producing open source hardware or useful for developing open source hardware. You don't have to be a hardware designer to contribute, we have a range of projects in the hardware or software realm, in a variety of programming languages.
