Reviews run for a minimum of one week. The outcome of the review is decided on this date. This is the last day to make comments or ask questions about this review.
OpenHW Group CORE-V Cores
CORE-V is a family open-source of microprocessor cores based on the RISC-V Instruction Set Architecture. The first two members of the family, CV32E and CV64A are derived from open-source implementations created by the PULP-Platform team at ETH Zurich.
OpenHW Group CORE-V Cores produces industrial quality fully documented and verified implementations of the CV32E and CV64A
The tangible products produced by OpenHW Group CORE-V Cores includes:
- Complete documentation: micro-architecture and a user manual.
- Implementation: RTL model and synthesis scripts for both ASIC and FPGA implementations.
- Verification: both dynamic (simulation) and static (formal) verification environments.
The open-source RISC-V Instruction Set Architecture created by UC Berkley and now maintained by the RISC-V Foundation inspired a growing community of open source hardware development. Some believe that RISC-V will do for hardware what Linux has done for software. The OpenHW Group is committed to this open source future and the Eclipse Foundation is a natural home for OpenHW projects.
The CV32E is derived from the PULP-Platform RI5CY project: https://github.com/pulp-platform/riscv
The CV64A is derived from the PULP-Platform Ariane project: https://github.com/pulp-platform/ariane
OpenHW Group has started development of CORE-V. The documentation is on GitHub at https://github.com/openhwgroup/core-v-docs and the code base is at https://github.com/openhwgroup/core-v-verif.
All products produced by the OpenHW Group shall be covered by one or more of:
- Solderpad Hardware License, SHL v2.0
- Apache License v2.0
- Eclipse Public License, v2.0
SHL is a permissive license implemented as a 'wrapper' around Apache v2.0. See https://solderpad.org/licenses/SHL-2.0 for more information.
Note that some artifacts may be covered by SHL v0.51 or soley Apache v2.0 only (not SHL).
The OpenHW Group is working to "tape-out" (release a build for silicon fabrication) in the second half of 2020. A more detailed schedule can be found at https://github.com/openhwgroup/core-v-docs/tree/master/cores.
