David Harris	d80cb36778	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

Ross Thompson	37078f3d9b	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

Ross Thompson	3bf2b35704	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.	2023-07-18 15:07:10 -05:00

Ross Thompson	340aac0934	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
