Bluespec, Inc. just released an updated version of the RISC-V Explorer, a free tool for quickly and accurately evaluating RISC-V open source cores. This is the second in a series of future releases to enable users to track relative changes in the features, performance, and size of the best RISC-V open source cores.
Hundreds of users have downloaded the RISC-V Explorer since it was first launched this past August. To download the latest version, visit The Free RISC-V Explorer page on Bluespec’s website.
The new release adds the OpenHW Group 4-stage CV32E40P core to the 200+ Piccolo, Flute and Rocket cores previously released. It also adds a new findcore search, filtering capabilities, and support for Ubuntu 18.04 LTS.
The next release will support the low-cost Arty A7 FPGA boards and add Bluespec’s new multi-cycle minimal footprint Magritte core. Stayed tuned for that release, coming soon!
OpenHW Group CV32E40P
The CV32E40P is a 4-stage RV32IMC core delivering 2.33 CoreMark/MHz when connected to 4KB instruction and data caches. The OpenHW Group’s mission is to produce silicon proven open source cores that can be used in commercial chips with the same confidence as proprietary IP. As such, the CV32E40P is written in exclusively SystemVerilog and is designed and verified using commercial toolchains.
“We are thrilled to have our CORE-V in Bluespec’s RISC-V Explorer,” says OpenHW Group CEO Rick O’Connor. “We want to empower as many users as we can to see what they can do with our RISC-V cores, and we welcome the open, transparent comparison of our cores to alternatives. Bluespec’s Explorer is a great way to do that.”
