This assembly routine calculates the square of an unsigned integer. How long does this take in clock cycles (worst case). Assume ARM 32 bit instruction set and the integer is in RO before we begin, AREA .text, CODE, READONLY Square PROC EXPORT quare MOVR1,RO; CMPR1, #0 ANDS R3,RO,R1 BNE skip ADD RO,R1, LSL R3; MOV R2,R2, LSL #1 CMP R2, #0 BNE loop BX LR Loop Skip ENDP ALIGN END Name one code change to the program makes it faster?
