The major modification in this release is the support of the write-back (WB) policy (in
addition to the write-through (WT) policy). The cache can either implement one of these
policies or both in a per-cacheline basis.

  • Added

    • Support of the WB policy.
    • Configuration parameters to choose between WT or WB, or both, at synthesis time.
    • Validation testbench compatible to Verilator.
    • Add a write-policy hint field in the request to select between WT and WB, dinamically.
  • Removed

    • WbufSendFeedThrough parameter removed
  • Changed

    • Arbitration between cacheable and uncacheable memory requests is done inside the
      HPDcache. The memory interface implements 5 channels, instead of 10.
    • The CMO type is into the operation field of the request (instead of the size field).
    • Select the victim cacheline at cache miss time (before was done on refill time). The
      slot is pre-allocated and written by the miss handler when the refill response arrives.
