a8a8422557 Updated parameterization types. Modelsim version 2022.1 did requires defaults to a 32 bit integer. The base and ranges for the address decoder need to be larger. 2023-06-09 09:28:24 -05:00
Ross Thompson
a963f0af3a Updated source code to be compatible with verilator 5.011 for lint only. 2023-05-31 10:44:23 -05:00

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

0020d94b39 Updated mmu's tlb and hptw to use Lim's parameterization. 2023-05-24 18:02:22 -05:00

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

930fb67308 Trying to figure out why the parameterization slowed down modelsim so much. 2023-05-24 12:44:42 -05:00

1b385c4336 Changed DIVN comparison from NF to NF+2. Shouldn't make a difference on our word sizes of XLEN=32/64, NF = 10/23/52) but is more proper in the general case. 2023-05-15 03:51:59 -07:00
