Question

Q1a) A task which takes ? seconds if accomplished by a single unit is pipelined into 8 subtasks instead. Each subtask completes in ?/8 seconds. How many seconds it will take for the pipeline to complete 90 tasks?

Q1b) The following question assumes that you are manipulating signed 2’s complement numbers of 6 bits. The leftmost bit is a 0 for positive numbers and a 1 for negative numbers. The other 5 bits code the magnitude of the integer, according to the 2’s complement system. The numbers represent A + B = C Solve the following for B

A = 001011

Answer 1

1.a)

It takes (90T)/8 seconds to complete the task.Since each task take T seconds to complete and each task is divided to 8 sub tasks.each sub task takes T/8 seconds. So 90 tasks so total time is 90T/8.
