Question
Write simple MIPS assembly code and simulate it using the simulator that was introduced in the lab (QtSpim). Write and execute a program that will copy a given 12 elements array into another. Both arrays are in memory. The first array should contain {0, 1, 2, 3, 4,..., 10, 11} and start at 0x 10010000. The second array should start at the end of the first array. Write and execute a program that finds the minimum of a given set of elements by looping over the set. The elements are stored in memory starting at 0x10010000 and contain {45, 56, 11, 1, 67, 42, 9, 34, 12, 11, 45}. Write and execute a program to add a and b, leaving the result in an leaving the b unmodified. Both a and b are 10 elements arrays stored in memory starting at 0x10010000. Lab Assignment: Provide comments throughout your code. Write a report, which includes: MIPS Code for each program Output Screen for registers/console for each program. Conclusion.Explanation / Answer
