INTRODUCTION
Definition
SIMD represents one of the earliest styles of parallel processing. The term SIMD stands for “Single-Instruction Multiple-Data,” The same instruction is executed by multiple processor using different data streams. Each processor has its own data memory, but there is single instruction memory and control processor, which fetches and dispatches instructions. SIMD aptly encapsulates the
