基于C++的数值转换
.globl main
main:
# 初始化
li t0, 0 # result=0
li t1, 0 # i=0
loop:
# 判断循环条件i<colCnt
bge t1, colCnt, end
# 计算result=pA[i]*pB[i]
slli t2, t1, 2 # t2 = i*4
add t3, pA, t2 # t3 = pA + i*4
add t4, pB, t2 # t4 = pB + i*4
lw t5, 0(t3) # t5 = *(pA + i*4)
lw t6, 0(t4) # t6 = *(pB + i*4)
mul t7, t5, t6 # t7 = t5*t6
add t0, t0, t7 # result += t5*t6
# 更新循环变量i++
addi t1, t1, 1
j loop
end:
# 返回result
mv a0, t0
ret
