beb95dd592 Modified the pmachecker to correctly check the permissions for cmo instructions.
However this isn't fully tested.

f6a7f707bd Fixed test cases for medeleg issue 444. Also added a COMPRESSED_SUPPORTED parameter true when C or Zca is supported, and use this to get compressed hardware such as the spill logic and the +2 adder. 2023-10-30 09:56:17 -07:00

28752303be Added ZCA/ZCF/ZCD/ZCB support. Doesn't break regression, but not tested. Need to get tests for Zcb. Draft tests are in riscv-arch-test but not yet committed there 2023-10-04 12:28:12 -07:00

d04d2afed2 Modified the LSU/IFU and caches to improve critical path. Arty A7 went from 15 to 17Mhz. I believe we can push all the way to 20+Mhz with relatively little effort. Along the way I'm fixing up the scripts build the linux images for the flash card. 2023-07-21 13:06:27 -05:00

538efaf771 Optimized critial path in ifu's spill logic. 2023-07-19 14:13:46 -05:00

b756b248b4 Wow. The newest version of Vivado does not like the enums as parameters.
The solution is simple.  I changed the type to logic [31:0] and defined macros for the branch predictor types as 32 bit integers.

04d0fd94f0 Merge branch 'param-lim-merge' 2023-05-26 16:25:35 -05:00
Ross Thompson
1315a0bf4a Got the branch predictor parameterized using Lim's method. Also had to add a global enum included in both cvw.sv and the configs which defines the branch predictor types. This should be synthesizable, but I'll need to double check. 2023-05-26 16:00:14 -05:00

fcb1c63f5f Partial parameterization into mmu. 2023-05-24 16:12:41 -05:00

052bc95966 More parameterization. Copied Lim. Still no slow down. 2023-05-24 14:49:22 -05:00
Ross Thompson
b91b54589e Updated a large number of the source files to use parameters rather than `defines. Based on Lim's work. So far there is no simulation slow down. 2023-05-24 14:05:44 -05:00
