In this assignment you will write an ARM v$8$ assembly program that implements multiplication. For multiplication, youll implement$$the shift$-$and$-$add algorithm. You may not use any of the ARM$$arithmetic instructions, for any part of your program, no exceptions$($e$.$g$..$ add, sub, mul, div, neg, or any$$variants$)!$ For manipulating the stack pointer, you may use the stp and ldp instructions, as well as the ldr and str instructions with pre$-$ and post$-$indexing.You should implement$$the shift$-$and$-$add functions using only logical$/$move operations $($and$,$ eor, orr, cmp$,$ mov, lsl$,$ asr, lsr$,$ mvn$,$ etc.$),$ memory operations $($stp$,$ ldp$,$ str$,$ ldr$,$ stm$,$ ldm$,$ etc., automatic stack pointer updating allowed$),$ and branch instructions $($conditional$,$ unconditional, and function calls$).$ Your program must$$also be modular.
