Question #1 Marks 5 Convert 111000 & 111111 to decimal, assuming this is a number in: a) Signed magnitude format b) 1’s complement c) 2’s complement Question #2 Marks 10 1. What will be the ... value of accumulator register if PC=500, PC=501, PC=502, PC=503 and PC=504? Given that “0001” corresponds to fetching, “0100” correspond to addition and “0101” correspond to store Question #3 Marks 10 A processor processing a multimedia process for which it requires 2055 seconds. Each instruction consumes 8 seconds. During execution of 36th instruction two interrupts have occurred, First interrupt is of 120 seconds having 15 instructions. Second interrupt of main process consists of 180 seconds. Each of 0.6 sec. During the execution of 7th Instruction of 1st interrupt another sub-interrupt (3rd interrupt) has occurred of 360 sec and 18 instructions. a) Calculate the size of main process b) What is the time required to execute each instruction of 1st interrupt. c) Total no, of instruction in second interrupt d) Total no. of instructions in 1st interrupt e) Time to serve each instruction in 3rd interrupt f) Total time to serve 2nd interrupt including waiting its waiting time g) Total execution time of main process including all interrupts h) Waiting time of 1st interrupt i) Waiting time of 2nd interrupt j) Waiting time of 3rd interrupt [Show More]
