I was trying to use sbrk for dynamic memory allocation. But, being a newcomer to SPIM and MIPS, I was unable to do so. I sketched out a rough code for the same.
.data
var: .word 25
.text
main:
li $v0, 9
la $v0, var
lw $a0, var
syscall # DYNAMICALLY ALLOCATING MEMORY OF SIZE 4 BYTES AT ADDRESS OF VAR
sw $v0, var
li $v0, 10
syscall
.data
var: .word 25
.text
main:
li $v0, 9
lw $a0, var
syscall # DYNAMICALLY ALLOCATING MEMORY OF SIZE 4 BYTES AT ADDRESS OF VAR
sw $v0, var
li $v0, 10
syscall
Only the second statement needs to be omitted as the system is waiting to get a amount of byte that should be allocated but above I was trying to give the address of var but this is result. The sbrk service returns the address to a block of memory containing n additional bytes. This would be used for dynamic memory allocation.
