Complete Loop

Here is the loop with the branch delay slots filled. One could be clever and eliminate the last no-op, but let's not.

#
#  branch delay slots  filled
#
init:   
        ori    $8,$0,0        # count = 0

test:   sltiu  $9,$8,10       # count < 10
        beq    $9,$0,endLp    # end loop if count >= 10
        sll    $0,$0,0        # delay

                              # do stuff

        addiu  $8,$8,1        # count++ ;
        j      test
        sll    $0,$0,0        # delay

endLp:  sll    $0,$0,0        # branch target

The no-op at endLp is not filling a branch delay slot. It is there for convenience in running the program with SPIM.

With a few assembly language directives, the code is ready to run. Step through the code and watch $8 (count) increase from 0 to 0xA.
