SIMD (pronounced "sim-dee") is short forSingle Instruction/Multiple Data which is oneclassification of computer architectures. SIMD allows one same operation to be performed on multiple data points resulting in data level parallelism and thus performance gains — for example, for 3D graphics and video processing, physics simulations or cryptography, and other domains.

See alsoSISD for a sequential architecture with no parallelism in either the instructions or the data sets.
