50a92247b3 Finally I think I have the function radix mapping across all applications correctly. I still need to clean up the code a bit so it is easier to understand. 2021-03-10 11:00:51 -06:00

66e84f3a2c Merge branch 'bp' into main 
Concerns:
1. I don't think the correct data buses are going to the multiplier.
2. I'm not sure the FlushF signal is correct.

7592a0dacb Shreya and I found a bug with the exeuction of JAL and JALR instructions. The link was only set in the writeback stage. Once the branch predictor started correctly predicting JAL(R)s the ALU and forwarding logic need to have the PCLinkE at the execution stage in case an instruction in the next two clocks need the data. 2021-02-26 20:12:27 -06:00

c6ebe7733b Hacked the sram memory models to reset their internal registers. This allows the simulation to run but is only temporary. 
About 149307ns of simulation run.
