RISC-V News

Get Answers On Stack Overflow!

We now have a new Stack Overflow for RISC-V questions.To help lessen some of the technical support and troubleshooting questions that have been popping up on the mailing lists, we have added a “riscv” tag to http://stackoverflow.com/tags/riscv/.  This has a couple of advantages.  It reduces the traffic related to toolchain difficulties so we do not inundate users who want to discuss RISC-V at a more general level; it provides a Google-able…

Launching the Open-Source Rocket Chip Generator!

We are very excited to announce the alpha release of our Rocket chip generator. This generator toolkit can be used to create instances of our high-performance, energy-efficient Rocket processor suitable for both high-speed simulation and full synthesis. We have provided a collection of components that go well beyond simple pipeline RTL in order to allow you to generate a complete Rocket implementation, including a memory subsystem. What is Rocket? Rocket is a 5-stage…

RISC-V Analysis by Adapteva Founder

Andreas Olofsson is the founder of Adapteva and the creator of the Epiphany architecture and Parallella open-source computing project.  He has published his own analysis of the RISC-V ISA. Quoting the conclusion:“The RISC-V architecture is not revolutionary, but it is an excellent general purpose architecture with solid design decisions. The true breakthrough here is really the open source licensing model and the maturity of the design as compared to most other open…

RISC-V just got a new logo!

As we were getting ready for HotChips, we realized we were missing something very important: A logo!

Thanks to the creative designers at 99designs, we were able to get a pretty good logo in a week. The symbol visualizes RV, which we often use to abbreviate RISC-V when naming an ISA variant. The logo comes in two layouts. First, here’s the tall RISC-V logo:
