Rewrite the following MIPS program segment with an equivalent program segment that runs about $1000$ times faster.

sub:

lp:

ble $to$,$$$0,$ done # finished with loop?

Iw $t$1,$ incr # increment

add $t$2,$ $t$2,$ $t$1$ # $t $t$2+$ incr

addi $t$0,$ $t$0,-1$ # decrement loop counter

j lp # repeat

done:
