The BOOM Repository

The BOOM repository holds the source code to the BOOM core; it is not a full processor and thus is NOT A SELF-RUNNING repository. To instantiate a BOOM core, the Rocket-Chip generator found in the rocket-chip git repository must be used https://github.com/freechipsproject/rocket-chip, which provides the caches, uncore, and other needed infrastructure to support a full processor.

The BOOM source code can be found in boom/src/main/scala.

The code structure is shown below:
