ca546beaf8 We now have a solid rough draft of the 2 bit sat counter branch predictor with BTB and RAS.
This is not yet tested but the system verilog does compile.

935e9e59e9 added branch predictor 2 bit table + SRAM model. The SRAM model is only approximate, but it does correctly model the read and write pipelined behavior. 2021-02-14 15:13:55 -06:00

f1768ee50b Busybear: start checking CSRs
scounteren and mcounteren are currenly manually deleted from the CSRs list
(see slack channl #linux-bringup)

and 3 of the CSRs referenced are skipped because of weird locations for them

oh and this doesn't check their initial state, just their changing. This could be a problem
