Obviously, QtSpim simulates a single core processor. Assume (hypothetically) that there is a version of QtSpim that simulates a 4-core processor. Write a MIPS Assembly program that would take advantage of the 4 cores to speed up the execution of mathematical calculations. Specifically, write a program that receives as input two arrays of equal length, and replaces the content of each element in Array 1 with the sum of the corresponding elements in Array 1 and 2. Naturally, you will not be able to test the execution of your code. Instead, provide extensive comments throughout the hypothetical code. In addition, create diagrams that illustrate the execution (the values of your key variables and arrays). Since your program will consist of parallel iterative loops, show diagrams for the first 3 cycles, the middle cycle, and the last 3 cycles of the hypothetical program. Assume that the hypothetical processor implements the same exact Assembly as the single core MIPS, with the ability to execute certain types of instructions in parallel.

Required:
Calculate the hypothetical performance gain vs a single core MIPS and account for at least 3 overhead factors. Explain your assumptions, choices, and calculations, in detail in a separate document.
