Flynn's taxonomy

Duncan proposed modifications to Flynn's taxonomy to include pipelined vector processes.

Flynn's taxonomy - View diagram comparing classifications.

Flynn's taxonomy is a classification of computer architectures, proposed by Michael J. Flynn in 1966.

SISD is one of the four main classifications as defined in Flynn's taxonomy.

Single instruction, multiple data (SIMD), is a class of parallel computers in Flynn's taxonomy.

Michael J. Flynn created one of the earliest classification systems for parallel (and sequential) computers and programs, now known as Flynn's taxonomy.

In Flynn's taxonomy, this strategy is known as Multiple Instructions-Multiple Data or MIMD.

(called "SIMD" in Flynn's taxonomy) The difference is analogous to the difference between scalar and vector arithmetic.

Using Flynn's taxonomy, these two schemes of dealing with data are generally referred to as SIMD (single instruction, multiple data) and SISD (single instruction, single data), respectively.

This scheme uses the SIMD (Single Instruction Stream, Multiple Data Stream) category from Flynn's Taxonomy as a root class for Processor Array and Associative Memory subclasses.
