SIMD

In computing, SIMD (Single Instruction, Multiple Data) is a technique employed to achieve data level parallelism, as in a vector or array processor. First made popular in large-scale supercomputers (as opposed to MIMD parallelization), smaller-scale SIMD operations have now become widespread in personal computer hardware. Today the term is associated almost entirely with these smaller units.
