MIPS汇编程序判断素数的实现方法如下:
.data
msg1: .asciiz "Enter a number: "
msg2: .asciiz "The number is prime."
msg3: .asciiz "The number is not prime."
.text
.globl main
main:
li $v0, 4 # print string
la $a0, msg1
syscall
li $v0, 5 # read integer
syscall
move $t0, $v0 # save input number to $t0
li $t1, 2 # initialize divisor to 2
li $t2, 0 # initialize remainder to 0
loop:
div $t0, $t1 # divide input number by divisor
mfhi $t2 # get remainder
beq $t2, $0, not_prime # if remainder is 0, number is not prime
addi $t1, $t1, 1 # increment divisor
blt $t1, $t0, loop # if divisor is less than input number, continue loop
j is_prime # if divisor is greater than or equal to input number, number is prime
not_prime:
li $v0, 4 # print string
la $a0, msg3
syscall
j end
is_prime:
li $v0, 4 # print string
la $a0, msg2
syscall
end:
li $v0, 10 # exit program
syscall
