71ed49bf2b cleanup of signal names. 2022-02-16 15:29:08 -06:00
Ross Thompson
27042f028e Modified lsu and uncore so only 1 sww is present. The sww is in the LSU if there is a cache or dtim. uncore.sv contains the sww if there is no local memory in the LSU. This is necessary as the subword write needs the read data to be valid and that read data is not aviable in the correct cycle in the LSU if there is no dtim or cache. Muxing could be done to provide the correct read data, but it adds muxes to the critical path. 2022-02-16 15:22:19 -06:00
