Detailed explanation-1: -It is the reciprocal of the clock frequency. For example, a 1 GHz processor has a cycle time of 1.0 ns and a 4 GHz processor has a cycle time of 0.25 ns.
Detailed explanation-2: -Remember : 1 Hertz = 1 Hz = 1 cycle/sec. To determine the length of a clock cycle, divide clock speed into 1. One clock cycle is 1 / ( 1 * 10^6 cycles/sec. ) or 1/1 * 1/(10^6 cycles/sec). 1 over a power flips the units and the sign is inverted, so 1/10^6 cycles/sec becomes 10^-6 secs/cycle.
Detailed explanation-3: -The clock rate is the reciprocal of clock cycle-a frequency, how many cycles per sec (eg, 100MHz). 1/10ns = 100, 000, 000 = 100MHz (clock rate).
Detailed explanation-4: -1) If a computer has a clock cycle time of 5ns, Find the clock rate. Cycle time= 5ns, clock rate= 1/cycle time. Q. 2) CPU clock rate is 1MHz.
Detailed explanation-5: -Calculation of IPC The number of instructions per second and floating point operations per second for a processor can be derived by multiplying the number of instructions per cycle with the clock rate (cycles per second given in Hertz) of the processor in question.
