3. Consider two different processors P1 and P2 executing the same instruction set with the clock rates and CPls given in the following table. 1. If the processors each execute a program in 15 seconds, find the number of cycles and the number of instructions for each processor 2, We are trying to reduce the program execution time by 20%, but this leads to an increase of 25% in the CPI. What clock rate should we have to get this time reduction for each processor Processor Clock Rate P1 P2 4 GHz 2 4.5 GHz 1.5 You may find this table of clock cycle times and clock rates useful: Time Measurement Time Unit Frequency Unit Seconds (s Hertz (Hz) 10-3 Milliseconds (ms) 103 Kilohertz (kHz) 10-6 Microseconds (us) Megahertz (MHz) 10-9 Nanoseconds (ns) 109 Gigahertz (GHz) 10-12 Picoseconds (ps) 1012 Terahertz (THz)
