iMesh, the Tile Processor Architecture's on-chip interconnection network, connects the multicore processor's tiles with five 2D mesh networks, each specialized for a different use. Taking advantage of the five networks, the c-based iLib interconnection library efficiently maps program communication across the on-chip interconnect. The Tile Processor's first implementation, the TILE64, contains 64 cores and can execute 192 billion 32-bit operations per second at 1 GHz.
