PLEASE!!! READ THE QUESTION CAREFULLY FIRST, I HAVE LOST MANY QUESTIONS BECAUSE THEY SIMPLY DONT READ THE QUESTION AND GIVE the WRONG ANSWER.
THANKS. AND PLEASE LABEL PROPERLY.
Proiect 2: MIPS SIM on Pvthon For this project, you will work in group to implement a python program, which takes as input a text file containing some MIPS code (represented as machine code in hex), and simulate the running of this program, similar to MARS, and output the results. Your project should eventually show three components: 1) a Python simulator, 2) a number of test cases in MIPS machine code, and 3) a PRPG program in MIPS machine code, where 2) and 3) should successfully run on 1). 1) Specifics for the Python simulator simulator shoul Minimum subset of instructions: .Other allowed instructions that your PRPG might use: .One "special instruction" of your choice, if you decide to pursue the 10pts extra credit *Registers: o addi, addu, sub, slt, and, ori, sll, srl beq, bne, lw, sw o add, slti, sltu, lui, andi, or, xor, xori, j o Needed to be approved by the instructor o $0 (always 0) o $8$23 o PC: starting at 0, increment by 4 Minimum memory address range: o [0x2000, 0x2050] .

Your python code should be able to report the same MARS shows the content of memory, from 0x2000 on, in increment of 4.

Which PRPG algorithm did your group choose? Why? (up to 5pts will be given to the group(s) which chose the rarest PRPG algorithm.) Q2: How do you verify the correctness of your python simulator, and PRPG code? What kind of resources (productivity tools, collaboration tools) did your group use to work on this project? Give an example of a bug (either in MIPS or python) that your group found out.

Working with a special instruction that is not supported by MIPS can be hard to verify- you cannot try it on MARS and see if your result is correct. How did you ensure that the code is correct and the debugging process is easy to handle? Provide a comparison for two versions of the same PRPG algorithms, with and without your special instruction, for the above 6 seeds, to show the difference in Instruction Count. You will need also to attach the two prpg_w_special.txt and prpg_wo _special.txt file in your report and Bb submission.
