add $t0, $zero, $zero
#$s0 contains the address of the first element of the first array
lui $s0, 0x1001
ori $s0,$s0,0
#$t0 contains the address of the first element of the second array
lui $t0, 0x1001
ori $t0, $t0, 0x0040

Filling in the Program |
Assume that you have an array of 10 elements with base address in $s0. Assume that the base address of the second array is in $t0. Copy the elements from the first array to the second. In order to receive full credit you must use a loop to traverse the elements of the arrays.

Executing the Program |
Once you have saved the program template, you can write the code, assuming that the base address of the source array is in $s0 and the base address of the destination array is in $t0.
Details about executing the program can be found in the Lab 1 page.
Note:
Once you find that you have to make changes to your code, make the changes in a text editor, then reinitialize the simulator [Simulator -> Reinitialize], and load the file again [File->Open]
Turning In Your Code |
Turn in your code by emailing it to the TA, Yuly, at ysuvorov@iastate.edu. The subject line of your email should be "Comp Sci 321 Lab 3" and you should paste the assembly code into the message body - no attachments please.
