When determining the size of .asciiz string, should I take into consideration the terminating character ? For example: .data string: .asciiz "Hello" The size of "string" is 5 or 6 (byte) ? Thank you in advance. if you are asking about how many bytes in memory the string is stored in then it's 6 bytes if you are asking about what should be returned by a function that count the string length (strlen C function for example) it should be 5 This particular asciiz string requires 6 bytes of storage. In programming situations, you will measure the string size to be 5. As in strlen() . When using this

How can I read an integer into a local variable in MIPS ? Is it possible? The problem asks me to use the concept of assigning integer variables as local variables. #A question from my text book. And by the way , not a homework! Thanx in advance! :D li $v0, 5 syscall move $t0, $v0 The value is now in $t0. This will read the integer from the console. 来源： https://stackoverflow.com/questions/6900762/reading-an-integer-into-a-local-variable-in-mips

I am working on a little mini compiler while trying to learn some MIPS here. Here's my issue: MIPS has an instruction li (load immediate) which would work like this li $5,100 which would load 100 into register 5. However, I need to load floats into registers right now and am struggling with figuring out a way to do it...since li $5,2.5 does not work. Anyone have any advice? I am working in C, I was thinking I could somehow get the integer representation of the float I am working with (i.e. so the floats binary representation == the ints binary representation) then load the "integer" into the

I'm trying to compute (a * c) - (b / d), and so far my assembly code is: .data A: .word 5 B: .word 6 C: .word 3 D: .word 2 .text lw $t0, A lw $t1, C mul $t0, $t0, $t1 lw $t1, B lw $t2, D div $t1, $t1, $t2 sub $t0, $t0, $t1 li $v0, 1 move $a0, $t0 syscall li $v0, 10 syscall But when I run it, I get the error. I am new to QTSpim and assembly so I would appreciate some help if possible. Thank you! edit: the exact error is: "Instruction references undefined symbol at 0x00400014 [0x00400014] 0x0c000000 jal 0x0000000 [main] ;188: jal main" The default startup code expects your program to have a
