A Study of Techniques to Increase Instruction Level Parallelisms

Abstract

Instruction Level Parallelism (ILP) is the number of instructions that can be executed in simultaneously a program in a clock cycle. The microprocessors exploit ILP by means of several techniques that have been implemented in the last decades and according to the advances that have been obtained in hardware, this survey presents the different techniques that have been used successfully in the execution of multiple instructions of a single program in a single clock cycle.
