For a single cycle Processor, how many clock cycles are required to execute the following code segment that clears a string of length Sbytes ($a1=5) ? Bzero beq Sa1, Szero, End Loop: sb Szero, O($a0) # sb store byte in memory add Sa0, $a0, 1 sub $a1, $a1, 1 bne Sal, Szero, Loop End : jr Sra #jump to an instruction with an address given in register $ra (3 Puan) 4 Consider the MIPS code segment, s 512 511,8 sri $13, 511,1 sub St1, St2.
