CV-HPDCACHE
Summary
Development and verification of a High-Performance L1 Dcache integrated with the CVA6.
Activities and progress since last report:
-
Achievements:
- Functional integration with OpenPiton running Linux with up to 64 cores !
- Several features implemented in the HPDcache to support tiny embedded configurations: single entry MSHR, pseudo random replacement policy (using a 8-bit LFSR).
- Thales DIS is doing a parameter exploration of the HPDcache to target tiny embedded systems. They achieved better area results than with the WTDcache. Therefore, they are switching to the HPDcache for future products (together with the CVA6 core).
- First complete version of the HPDcache User Guide in ReadTheDocs format (restructured text). Not yet published in the OpenHW ReadTheDocs server.
-
Planned:
- Still working in the delivery of a preliminary testplan. We targeted end of march but we will probably have a 4 or 5 weeks delay due to internal staff planning.
- Working in the delivery of a preliminary testbench
- J. Balkind, N. Oliete, and myself are proposing a Google Summer of Code projet to integrate the HPDcache also as an instruction cache. Target cores: CVA6, Sargantana, and/or Lagarto cores.
