[英]adding two numeric strings - MIPS ASSEMBLY
I am working on a MIPS Assembly program. 我正在研究MIPS汇编程序。 I am new at this, and am having some trouble. 我对此很陌生,遇到了一些麻烦。
How do you convert digits in a .asciiz string to there numeric counter parts. 如何将.asciiz字符串中的数字转换为数字计数器部分。
EX: "1" -> 49 例如:“ 1”-> 49
Assuming you use a simulator like http://sourceforge.net/projects/spimsimulator/ : 假设您使用http://sourceforge.net/projects/spimsimulator/之类的模拟器:
.data
input: .asciiz "1234"
.text
main:
la $t0, input # load address of input
loop:
lb $a0, ($t0) # load one byte
beq $a0, $0, exit # exit if null-byte
li $v0, 1 # print integer system call
syscall
addi $t0, $t0, 1 # increment address
j loop
exit:
jr $ra
Output: 49505152 输出:49505152
