Concept, Design and Performance Evaluation of VLVIW Processor

EPIC processor is one of the best ways to exploit the instruction level parallelism where multiple instructions are issued explicitly by the compiler. VLIW processor is the evolution of EPIC processing paradigm. Very Long Instruction Word (VLIW) is multi-issue processors that try to extract parallelism statically by the compiler .It execute a long instruction that consist of multiple operation. Even if VLIW processor provides higher performance than conventional processor some of application like scientific computing, Digital signal processing, military application may need more processing speed. If instruction set is customize in such a way that its instruction would probably operate on linear array of number (also called as vector) instead of scalar operand, then performance could be increased tremendously. So a VLIW processor can be customize to work as a VLVIW processor which may result in high performance computation.
