Performance Modelling $-$ RISC$-$V processor

This project will require you to implement cycle$-$accurate simulators of a $32-$bit RISC$-$V processor in C$++$ or

Python. The skeleton code for the assignment is given in file $($NYU$\_$RV$32$I$\_6913.$cpp or

NYU$\_$RV$32$I$\_6913.$py$).$

The simulators should take in two files as inputs: imem.text and dmem.txt files

The simulator should give out the following:

cycle by cycle state of the register file $($RFOutput$.$txt$)$

Cycle by cycle microarchitectural state of the machine $($StateResult$.$txt$)$

Resulting dmem data after the execution of the program $($DmemResult$.$txt$)$

The imem.txt file is used to initialize the instruction memory and the dmem.txt file is used to initialize the

data memory of the processor. Each line in the files contain a byte of data on the instruction or the data

memory and both the instruction and data memory are byte addressable. This means that for a $32$ bit

processor, $4$ lines in the imem.txt file makes one instruction. Both instruction and data memory are in

"Big$-$Endian" format $($the most significant byte is stored in the smallest address$).$

The instructions to be supported by the processor are categorized into the following types:

The simulator should support the following set of instructions.

Tasks:$1)$ Draw the schematic for a single stage processor and fill in your code in the to run the simulator. $(20$points$)2)$ Draw the schematic for a five stage pipelined processor and fill in your code to run the simulator. The$$processor should be able ot take care of RAW and control hazards by stalling and forwarding. $(20$points$)3)$ Measure and report average CPI, Total execution cycles, and Instructions per cycle for both these cores$$by adding performance monitors to your code. $($Submit code and print results to console or a file.$)(5$points$)4)$ Compare the results from both the single stage and the five stage pipelined processor implementations$$and explain why one is better than the other. $(5$ points$)5)$ What optimizations or features can be added to improve performance? $($Extra credit $1$ point$)$
