Simulation and Investigation on “Effect of Dependency in under Pipelining”
Renuka Patel, Sanjay Kumar · International Journal of Computer Applications · 2016
Instruction level parallelism is the most common technique to achieve speedup and Pipelining is one of the techniques to achieve Instruction level parallelism.Pipelining is of 5 types -Scalar pipelining, Superscalar pipelining, Super pipelining, Under pipelining and Super Scalar Super pipelining.In pipelining technique more than one instruction can issue simultaneously into different functional unit.But, dependency is most common problem in pipelining.This paper shows the development of simulator using ‗C' language to study the effect of dependency in under pipelining.This paper also calculates some pipelining parameters like CPI, IPC etc.
