370a075fa1 Partial cleanup of memories. 2022-03-30 11:09:21 -05:00

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

fc2b4453ec rv32gc and rv64gc now use the updated ram3.sv (will rename to ram.sv) which uses a vivado block ram compatible memory. Still need to update simpleram.sv to use this block ram compatible memory. 2022-03-29 23:48:19 -05:00

7099259ff7 I think this version of csri matches what is required in the spec. ExtIntS should not be written into the SEIP register bit. 2022-03-25 13:10:31 -05:00

7a824eaae1 Found a way to remove a bus input into MMU. PAdr can be made into VAdr by selecting the faulting virtual address when writing the DTLB. 2022-03-24 23:47:28 -05:00
