Tile processor

From Wikipedia, the free encyclopedia

Tile processors are multicore or manycore chips that contain one-dimensional, or more commonly, two-dimensional arrays of identical tiles. Each tile comprises a compute unit (or a processing engine or CPU), caches and a switch. Tiles can be viewed as adding a switch to each core, where a core comprises a compute unit and caches.

In a typical Tile Processor configuration, the switches in each of the tiles are connected to each other using one or more mesh networks.[1] The Tilera TILEPro64, for example, contains 64 tiles. Each of the tiles comprises a CPU, L1 and L2 caches, and switches for several mesh networks.

Other processors in a tile configuration include SEAforth24, Kilocore KC256, XMOS xCORE microcontrollers, and some Massively parallel processor arrays.
