SIMD is the abbreviation for Single Instruction Stream, Multiple Data . SIMD is a term proposed by Michael J. Flynn and refers to the functionality that allows you to execute one instruction on multiple data “streams.” SIMD can potentially improve the performance of your programs. SIMD is a form of parallel computing; however, in some cases, the execution on the different data streams can happen sequentially, depending on the hardware functionality and the instructions to be executed.
