在首地址为 ARY 的宇数组中存放若干数据 (100，-150，65, 450， 80,300， 120，600，800，0,-120，200），编写程序求它们的平均值放于V字单元，并统计有多少个数大于此平均值，调用显示子程序将统计结果用十进制显示出来用32位汇编语言写出

以下是使用MIPS汇编语言的实现：

.data
ARY: .word 100, -150, 65, 450, 80, 300, 120, 600, 800, 0, -120, 200
V: .word 0
msg1: .asciiz "The average value is "
msg2: .asciiz "The number of values greater than average is "
newline: .asciiz "\n"

.text
.globl main

main:
    # load the constants
    la $t0, ARY # load the address of ARY into $t0
    lw $t1, V # load the address of V into $t1

    # calculate the average value
    li $t2, 0 # initialize sum to 0
    li $t3, 12 # initialize count to 12
    li $t4, 4 # set the increment to 4 bytes
    loop:
        lw $t5, ($t0) # load the next value from ARY
        add $t2, $t2, $t5 # sum the values
        addi $t0, $t0, $t4 # increment the address
        addi $t3, $t3, -1 # decrement the count
        bgtz $t3, loop # loop while count > 0
    div $t2, $t2, 12 # divide the sum by the count
    sw $t2, ($t1) # store the average value in V

    # count the number of values greater than the average
    li $t6, 0 # initialize count to 0
    la $t0, ARY # load the address of ARY into $t0
    loop2:
        lw $t5, ($t0) # load the next value from ARY
        bgt $t5, $t2, greater # branch if greater than average
        addi $t0, $t0, $t4 # increment the address
        addi $t3, $t3, -1 # decrement the count
        bgtz $t3, loop2 # loop while count > 0
        j done # jump to the end
    greater:
        addi $t6, $t6, 1 # increment the count
        addi $t0, $t0, $t4 # increment the address
        addi $t3, $t3, -1 # decrement the count
        bgtz $t3, loop2 # loop while count > 0
    done:

    li $v0, 4 # set the syscall code for printing a string
    syscall # print msg1
    lw $a0, ($t1) # load the average value into $a0

    syscall # print the average value
    la $a0, newline # print a newline

    la $a0, msg2 # load the address of msg2 into $a0
    li $v0, 4 # set the syscall code for printing a string
    syscall # print msg2
    move $a0, $t6 # move the count into $a0
    li $v0, 1 # set the syscall code for printing an integer
    syscall # print the count
