Detailed explanation-1: -Solutions for If a processor clock is rated as 1250 million cycles per second, then its clock period is a)1.9 * 10-10secb)1.6 * 10-9secc)1.25 * 10-10secd)8 * 10-10secCorrect answer is option ‘D’.
Detailed explanation-2: -A processor having a clock cycle time of 0.25 nsec will have a clock rate of 4000MHz.
Detailed explanation-3: -1 MHz = 1 * 10^6 cycles/sec. 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).
Detailed explanation-4: -Explanation: An optimizing compiler is a compiler designed for the specific purpose of increasing the operation speed of the processor by reducing the time taken to compile the program instructions.
