Question

MIPS Assembly

Vector (array) addition

Create, in the memory, the following two 2-integer arrays (vectors): Array(A), Array(B).

*****PLEASE USE MIPS FOR THIS PROGRAM ONLY*****

Create, in the memory, the following two 2-integer arrays (vectors): Array (A), Array(B). Array (A) = [2 3], Array (B) = [4 5] (a) Add the two created arrays (vectors): Array (A) + Array (B) = Array(C). (b) Print (console) the elements of the resulting vector [Array(C)].

Answer 1

Program Screenshot:

.data #declare the variables arrayA: word 2, 3 #create array A in the memory array B: word 4, 5 #create arrayB in the memory arrayC: word 0, 0 #declare array C sentence: .asciiz "The elements of Array C:\n" newLine: .asciiz "\n" .text addi $t0,$zero,0 #initailze $t0 with 0 i $s0,0 #initailze $s0 with 0 #finds the sum of arrayA and arrayB #and stores the result in arrayC findSum lw $t1,arrayA($t0) #get the initial address of arrayA into $t1 lw $t2,array B($t0) #get the initial address of arrayB into $t2 add $s0,St1,$t2 #find the sum of St1 and St2 sw $s0,arrayC(St0) #store the sum value into arrayc beq St0,4,finish Loop # if t0 is 4 than go to finish Loop add St0,$t0,4 #increment $t0 by 4 to get next value of the array j findSum #jump to findSum

finishLoop #printArrayC the sentence i$v0,4 la $a0,sentence syscall li $t0,0 #initailze $t0 with 0 #prints the value of arrayC printArrayC #get the initial address of arrayC into $t1 lw $t1,arrayC(St0) i$v0,1 move $a0,St1 syscall beq $t0,4,endProgram # if t0 is 4 than go to endProgram #print a new line li$v0,4 la $a0,newLine syscall add St0,$t0,4 #increment $t0 by 4 to get next value of the array. j printArrayC #jump to printArrayC again #ends the prgram endProgram liSv0,10 syscall
