TILE64 is a multicore processor manufactured by Tilera. It consists of a mesh network of 64 "tiles", where each tile houses a general purpose processor, cache, and a non-blocking router, which the tile uses to communicate with the other tiles on the processor.
The short-pipeline, in-order, three-issue cores implement a MIPS-inspiredVLIW instruction set. Each core has a register file and three functional units: two integer arithmetic logic units and a load-store unit. Each of the cores ("tile") has its own L1 and L2 caches plus an overall virtual L3 cache which is an aggregate of all the L2 caches. A core is able to run a full operating system on its own or multiple cores can be used to run a symmetrical multi-processing operating system.
TILE64 has four DDR2 controllers, two 10-gigabit Ethernet interfaces, two four-lane PCIe interfaces, and a "flexible" input/output interface, which can be software-configured to handle a number of protocols. The processor is fabricated using a 90 nm process and runs at speeds of 600 to 900 MHz.
According to CTO and co-founder Anant Agarwal, Tilera will target the chip at networking equipment and digital video markets where the demands for computing processing are high.
Support for the TILE64 architecture was added to Linux kernel version 2.6.36. Non-official LLVM back-end for Tilera exists.
