a64a37d702 Merge of main with the new icache and the branch predictor. I believe there is a bug in the icache with unaligned memory access. The second part of the access is incorrectly relying on the PCF being the address of the next two bytes of the instruction. However this is not always the case as the branch predictor can get the wrong target address. The icache needs to generate the +2 address internally. 2021-03-30 23:18:20 -05:00

c780a25f92 busybear: better instrF checking 
So this now checks instrF only when StallD is low. @kaveh I'd love your
opinion on this. I don't know if this is a good idea or not. Ideally we
should probably be checking InstrRawD instead, but I kind of want to stay
checking the instr in the F stage instead of D for now. Idk if this is worth
staying in F, I can't really see any big downsides to checking the instruction in
D except that PCD isn't an external signal, but neither is StallD, so.....
Anyway I'd love others' thoughts on this

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

416b3fc96c Add PCW checking 
for now, doesn't check InstrW because it fails on compressed instructions

b7f63c1dc7 busybear: NOP out floating point instructions for now 
Why does linux even try to do float stuff doing booting??
also, now runs the first 100k instructions!

4358f086be update busybear testbench to conform to new structure 
aaaaaaaaaaaaaaaaaahhhh so many changes

also the testbench now uses another internal signal,
which I don't like, but I can't think of a better option rn

619dec1490 busybear: simulate first 10k instructions 
I know we need to add CSR checking sometime soon
Also I'm a bit sketpical this is all working properly, and that no new bugs
were uncovered from 1k instrs to 10k instrs
