Detailed explanation-1: -The clock rate of the processor can be improved by a)Improving the IC technology of the logic circuitsb)Reducing the amount of processing done in one stepc)By using overclocking methodd)All of the mentionedCorrect answer is option ‘D’.
Detailed explanation-2: -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.
Detailed explanation-3: -Which is used to speed-up the processing: Pipeline.
Detailed explanation-4: -Hardware data prefetching is just one of these approaches. Hardware data prefetching bridges the gap by proactively fetching the data ahead of the cores’ requests to eliminate the idle cycles in which the processor is waiting for the response of the memory system.
Detailed explanation-5: -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.
