Question

Using SPIM, write a program to count the number of odd numbers of adata array. As
shown in the assembly code below, a 20-word data array is allocatedin the data segment
in memory; it contains 20 integers.
The inputs to the program would be 2 numbers which indicate thestarting index and the
ending index of the part of the array to be parsed. Please notethat the starting_index
should be less than ending_index. Eg. If the array has 23, 34, 37,45, 56, 67 and the
inputs are 2 and 5, the considered numbers for parsing would be 34,37, 45, 56. The
output needs to be 2 as there are 2 odd numbers in the selectednumbers.
The outline of the code is provided that will help you take in theinput and print the
output. The choices entered as input are available in $t0 (startingindex) and $t1
(ending_index).
Add your code after begin: and before done:
The result should be stored in register $t2 and then printed out bythe already available
code.
(Hint: you can use instruction la $s0, item to load the address ofthe first word of
the array into register $s0.)
Complete the assembly program shown on the next page and submit,via ANGEL, the
completed and tested program. You may assume that only legal inputswill be provided.
Both you and your programming partner should submit the programmaking sure to
include in your comments the name of the person whom you workedwith. One point of
extra credit will be given for the programs with the fewest numberof source (i.e.,
assembler) instructions (not counting the input and output codeprovided). Please report
in your comments the number of source instructions and the numberof instructions
executed.
Note: Remember that it is a good idea to have a working version ofthe basic solution
before attempting the extra credit versions.
