Hi guys, I have wrote a function in MIPS which is supposed to copy some words from memory and saving it to another memory address using assembly. The source address, destination address and the number of words to copy are input arguments of the function. I have used $a0 to $a2 for arguments as follows: $a0 = The source address, $a1 = destination address $a2 = the number of words to copy are input arguments of the function. Code: # UNTITLED PROGRAM .data # Data declaration section .text .globl main main: # Sta$t1 of code section funct: beq $a2,0,done lw $t1,($a0) sw $t1,($a1) add $a0,$a0,4 add $a1,$a1,4 sub $a2,$a2,1 j funct done: add $v0, $a1, $0 #nop jr $ra #return to the main program # END OF PROGRAM # END OF PROGRAM Now the problem I have is I get Exceptions when I run the code. Is a function supposed to have .main, .text, .data parts in the file? how can I write a main program which calls this function to copy few hundred words from memory address for example 0x50000 to 0x90000. Cheers guys, I have been stuck on this for a day now =(
