This question pertains to loop unrolling $($and not SIMD$)$ and multi$-$issue data paths. You must use MIPS.

$1.(4$ points$)$ Provide high$-$level language code for an IAXPY operation. You must state your function prototype and it must be consistent throughout this section.

$2.(8$ points$)$ Convert your high$-$level language code from the previous question to assembly language. Do not use System V ABI, you are constrained by the following:

$$ Input arguments $($pointers and scalars$)$ are placed in reverse order in the temporary

registers.

$$ The scratch registers you can use only are $s$0,$ $s$3,$ and the input and output registers. Assume that since these registers are scratch you do not need to preserve their values on the stack $($it had already been done for you$).$

$$ Any local variables you use begin at SP $+127$ on the stack.

$3.(8$ points$)$ Unroll your assembly code from the previous question to a loop factor of $2$

$4.(8$ points$)$ Arrange your unrolled assembly code from the previous question into issue packets for a static multi$-$issue processor that has the following data paths:

$$ Two data paths that can execute any command but memory operations.

$$ One data path that can only load from memory.

$$ One data path that can only store from memory.
