Engineers and scientists working on American military research programs can now access RISC-V processor core designs and associated blueprints through DARPA’s Toolbox, and use the technology in their prototypes and experiments.
The RISC-V chip designs will be provided by SiFive, which late last week announced a Toolbox licensing agreement with DARPA aka the US government’s Defense Advanced Research Projects Agency.
Toolbox attempts to lower the barriers and costs for entry into the world of chip design and manufacturing, at least for DARPA projects.
