Berkeley Out-of-Order Machine (BOOM)
|
||||
==============================================
|
||||
|
||||
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.
|
||||
|
||||
BOOM is heavily inspired by the MIPS R10k and the Alpha 21264 outoforder processors. Like the R10k and the 21264, BOOM is a unified physical register file design (also known as “explicit register renaming”).
|
||||
|
||||
Conceptually, BOOM is broken up into 10 stages: Fetch, Decode, Register Rename, Dispatch, Issue, Register Read, Execute, Memory, Writeback and Commit. However, many of those stages are combined in the current implementation, yielding seven stages: Fetch, Decode/Rename, Rename/Dispatch, Issue/RegisterRead, Execute, Memory and Writeback (Commit occurs asynchronously, so it is not counted as part of the “pipeline”).
|
||||
|
||||
Additional information about the BOOM micro-architecture can be found in the `BOOM documentation pages <https://docs.boom-core.org/en/latest/index.html>__`.

Generators
|
||||
============================
|
||||
Generator can be thought of as generalized RTL designs, written using a mix of meta-programming and standard RTL.
|
||||
This type of meta-programming is enabled by the Chisel hardware description framework embedded in Scala.
|
||||
A standard RTL design is esentially a degenerate form of a generator. However, by using meta-programming and parameter systems, generators can allow for integration of complex hardware designs in automated ways. The following pages introduce the generators integrated with the ReBAR framework.
