Rocket Core Generator
================================================================
Rocket Core
===========
Rocket is a 6-stage single-issue in-order pipeline that executes the 64-bit
scalar RISC-V ISA. Rocket implements an MMU that supports page-based virtual
@ -8,13 +8,9 @@ also has an optional IEEE 754-2008-compliant FPU, which implements both
single- and double-precision floating-point operations, including fused
multiply-add.
We plan to open-source our Rocket core generator written in Chisel in the near
future. We are currently in the process of cleaning up the repository. Please stay tuned.
Currently, a Rocket core with an 8 KB direct-mapped L1 instruction cache
and an 8 KB direct-mapped L1 data cache has been instantiated and committed to
the fpga-zynq infrastructure repository. A copy of the generated Verilog is available
[here](https://raw.githubusercontent.com/ucb-bar/fpga-zynq/master/hw/src/verilog/Slave.v).
This repository is not intended to be a self-running repository. To
instantiate a Rocket core, please use the Rocket chip generator found in the
rocket-chip git repository.
The following table compares a 32-bit ARM Cortex-A5 core to a 64-bit RISC-V
Rocket core built in the same TSMC process (40GPLUS). Fourth column is the
