The Berkeley Out-of-Order RISC-V Processor CircleCI

The Berkeley Out-of-Order Machine (BOOM) is a synthesizable and parameterizable open source RV64GC RISC-V core written in the Chisel hardware construction language. Created at the University of California, Berkeley in the Berkeley Architecture Research group, its focus is to create a high performance, synthesizable, and parameterizable core for architecture research. The current version of the BOOM microarchitecture (SonicBOOM, or BOOMv3) is performance competitive with commercial high-performance out-of-order cores, achieving 6.2 CoreMarks/MHz.

IMPORTANT: Using BOOM

This repository is NOT A SELF-RUNNING repository. To instantiate a BOOM core, please use the Chipyard SoC generator.

The current hash of Chipyard that works with this repository is located in the CHIPYARD.hash file in the top level directory of this repository. This file is mainly used for CI purposes, since Chipyard should follow the correct version of rocket-chip. For most users, you should be able to clone Chipyard separately and follow the default Chipyard instructions (without having to use the .hash file).

While BOOM is primarily ASIC-optimized, it is also usable on FPGAs. Chipyard provides infrastructure and documentation for deploying BOOM on AWS F1 FPGAs through FireSim.
