MIPS: Study "this supplied program" and fill in the missing code as indicated (via comments).

IMPORTANT: As indicated in the program's comments:

You ARE to write no more than certain number of lines of code as indicated. (One instruction per line, and there will be penalty if your code consumes more lines.)

Your code MUST use only instructions that are allowed (i.e., only bit manipulating instructions).

You MUST NOT in any way change the lines of code already written. ############################ data segment ################################ .data legend: .asciiz "0 = UpUp, 1 = UpLo, 2 = LoUp, 3 = LoLo " # UpUp = Uppercase-Uppercase, UpLo = Uppercase-Lowercase, ... inPrompt1: .asciiz "Enter 1st alphabet (A-Z; a-z): " inPrompt2: .asciiz " Enter 2nd alphabet (A-Z; a-z): " outLab1: .asciiz " and " outLab2: .asciiz " are " ############################ code segment ################################ .text .globl main main: li $v0, 4 la $a0, legend syscall # print legend la $a0, inPrompt1 syscall # print input prompt 1 li $v0, 12 syscall # read 1st alphabet move $t1, $v0 li $v0, 4 la $a0, inPrompt2 syscall # print input prompt 2 li $v0, 12 syscall # read 2nd alphabet move $t2, $v0 li $v0, 11 li $a0, ' ' syscall move $a0, $t1 syscall # 1st alphabet li $v0, 4 la $a0, outLab1 syscall # print " and " li $v0, 11 move $a0, $t2 syscall # 2nd alphabet li $v0, 4 la $a0, outLab2 syscall # print " are " li $v0, 1 li $a0, 0 # initialize desired output to 0 ########################################################## # Insert NO MORE THAN 7 lines of code that involve ONLY # bit manipulating instructions (ANDing, ORing, XORing, # NORing and shifting - only whatever that are needed) # so that the program will work just like the sample runs # shown at the bottom (some blank lines edited out). # HINT: Risking telling the obvious, the instructions you # insert are related to bringing the value in $a0 # from the initial value of 0 to the final desired # value (which should be either 0, 1, 2 or 3 when # printed as an integer). # You MUST test your completed program for AT LEAST the # test cases shown (and include the result in hardcopy). ########################################################## syscall # display desired output ########################################################## li $v0, 10 # exit gracefully syscall ########################## sample test runs ############################## # 0 = UpUp, 1 = UpLo, 2 = LoUp, 3 = LoLo # Enter 1st alphabet (A-Z; a-z): P # Enter 2nd alphabet (A-Z; a-z): M # P and M are 0 # -- program is finished running -- # # Reset: reset completed. # # 0 = UpUp, 1 = UpLo, 2 = LoUp, 3 = LoLo # Enter 1st alphabet (A-Z; a-z): A # Enter 2nd alphabet (A-Z; a-z): t # A and t are 1 # -- program is finished running -- # # Reset: reset completed. # # 0 = UpUp, 1 = UpLo, 2 = LoUp, 3 = LoLo # Enter 1st alphabet (A-Z; a-z): b # Enter 2nd alphabet (A-Z; a-z): E # b and E are 2 # -- program is finished running -- # # Reset: reset completed. # # 0 = UpUp, 1 = UpLo, 2 = LoUp, 3 = LoLo # Enter 1st alphabet (A-Z; a-z): q # Enter 2nd alphabet (A-Z; a-z): i # q and i are 3 # -- program is finished running -- ######################## end sample test runs ############################
