1993069986 Converted over to the blockram/sram memories. Now I just need to cleanup. But before the cleanup I wan to make sure the FPGA synthesizes with these changes and actually keeps the preload. 2022-03-30 11:04:15 -05:00

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
