498c2b589a Optimization of cache save/restore. 2022-02-04 14:21:04 -06:00
Ross Thompson
83fdedcec6 Working first cut of the cache changes moving the replay to a save/restore. 
The current implementation is too expensive costing (tag+linelen)*numway flip flops and muxes.

4a5aa43716 Merge branch 'makefiles' into main 2022-02-03 08:33:50 -06:00
Ross Thompson
55382be055 Completed makefile updates to accelerate the generation of memfiles. There are two makefiles in the 
regression directory.  Makefile calls the submakefiles for generating elf files.
The second makefile-memfiles generates the memfiles, addr, and label files.
