Author(s): Dave Reynolds

A class of parallel computers consisting of an array of small processors each executing the same instruction on its local data. The processors are often one-bit processors (a bit-serial array) and are often arranged in a regular lattice using hexagonal or square tessellation (with or without diagonals). Such arrays are particularly useful for simple image processing where each image pixel is generally assigned to a separate processor. Typical examples are DAP (from ICL), CLIP (from University College London), MPP (from Goodyear Aerospace) and GRID (from GEC). See Propagation in Cellular Arrays.
