This refers to a processor instruction that can perform operations across multiple data instructions. So, instead of saying Add A,B, you may say Add Row A, Row B or something to that effect. Instructions of this nature are often associated with 3D graphics and multimedia.
Single Instruction Multiple Data. Computer architecture that performs one operation on more than one set of data.
architecture a parallel processing architeture where more than one processor performs the same instruction on different data simultaneously. [SILC99
Single instruction multiple data -- a type of architecture for parallel computers
Single Instruction Multiple Data Industry
Single Instruction Multiple Data (SIMD) technique. This technique speeds up performance by using one instruction to process multiple data elements in parallel.
Definition by Charles Belov, 1997] Single Instruction Multiple Data. A single computer instruction perform the same identical action (retrieve, calculate, or store) simultaneously on two or more pieces of data.
Single Instruction, Multiple Data parallel computer performing the same operation, on different items of data at the same time. This operation is applied in lockstep. cf Vector, MIMD, SPMD
Single Instruction Multiple Data. CPU instructions that allow applications to obtain data from memory before the processor starts operating on it and lessen cache pollution by designating data for frequent use or for one-time only use.
Single-Instruction-Multiple-Data. A category in Flynn's taxonomy.
Single Instruction Multiple Data. A multi-processing architecture where individual processing elements perform the same instruction on many pieces of data, also referred to as a systolic array.
Single instruction multiple data. Category of applications in which homogeneous processes execute the same instructions on their own data.
Acronym for single instruction, multiple data. A parallel computer with a single thread of control broadcast across the plurality of execution units. Example: Thinking Machines CM-1.
A parallel programming model in which a multiple processors execute exactly the same instructions at exactly the same time, however each processor operates on different sets of data. See MIMD.
Abbreviation for single instruction, multiple data. SIMD is a technology incorporated into certain Intel microprocessors that extends the capabilities of these microprocessors to handle multimedia and communications software. This technology includes new instructions and data types that allows the microprocessor to process multiple data elements in parallel, thereby improving overall system performance.
Single Instruction, Multiple Data, an architecture that characterizes most vector computers. A single instruction initiates a process that sets in motion streams of data and results. The term is also applicable to parallel processors where one instruction causes more than one processor to perform the same operation synchronously, even on different pieces of data (e.g., ILLIAC). See also MIMD, SISD, and SPMD; for more information, see the "Taxonomy of Architectures" section of CTC's Parallel Processing Concepts module.
In computing, SIMD (Single Instruction, Multiple Data) is a technique employed to achieve data level parallelism, as in a vector or array processor. First popularized 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.
