Two simple MIPS QtSPIM questions

Learning Goal: I’m working on a programming discussion question and need an explanation and answer to help me learn.

  • Trace the following program by hand to determine the values of registers $f0 thru $f9. Notice that array1 and array2 have the same elements, but in a different order. Comment on the sums of array1 and array2 elements computed in registers $f4 and $f9, respectively. Now use the QTSPIM tool to trace the execution of the program and verify your results. What conclusion can be made from this exercise?





.globl main














li $v0, 10# To terminate the program


.end main


  • Write an interactive program that inputs the coefficient of a quadratic equation, computes, and displays the roots of the quadratic equation. All input, computation, and output should be done using double-precision floating-point instructions and registers. The program should handle the case of complex roots and displays the results properly. search for the form of the quadratic equation in the search engine
