If you want to increase the number of instructions executed per second for a processor, should you decrease the clock cycle time or increase the clock rate?
Added by Michael W.
Step 1
The clock rate (measured in Hertz) is the inverse of the clock cycle time. This means that a shorter clock cycle time results in a higher clock rate. Show more…

A program runs in 10 seconds on computer A, which has a 2 GHz clock. We are trying to help a computer designer build a computer, B, which will run this program in 8 seconds. The designer has determined that a substantial increase in the clock rate is possible, but this increase will affect the rest of the CPU design, causing computer B to require 1.2 times as many clock cycles as computer A for this program. What clock rate should we tell the designer to target? (2 Mark)

A microprocessor has an increment memory direct instruction, which adds 1 to the value in a memory location. The instruction has five stages: fetch opcode (four bus clock cycles); fetch operand address (three bus clock cycles); fetch operand (three bus clock cycles); add 1 to operand (three bus clock cycles); and store operand (three bus clock cycles). By what amount (in percent) will the duration of the instruction increase if we have to insert two bus wait states in each memory read and memory write operation? Repeat assuming that the increment operation takes 13 cycles instead of 3 cycles.
