Computer Architecture and Organization

1 Consider three different processors P1, P2, and P3 executing the same instruction set. P1 has a 3 GHz clock rate and a CPI of 1.5. P2 has a 2.5 GHz clock rate and a CPI of 1.0. P3 has a 4.0 GHz clock rate and has a CPI of 2.2 a. Which processor has the highest performance expressed in instructions per second? b. If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions. 2- Processor P1 clock cycle is 1nS. Processor P2 clock cycle is 2nS. P1 executes an instruction every two clocks. P2 executes an instruction per clock. Which processor runs faster
