TILE64
is a
VLIW ISA 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
A pipeline is a system of Pipe (fluid conveyance), pipes for long-distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries ...
, in-order, three-issue cores implement a
MIPS-inspired
VLIW instruction set
In computer science, an instruction set architecture (ISA) is an abstract model that generally defines how software controls the CPU in a computer or a family of computers. A device or program that executes instructions described by that ISA, s ...
. Each core has a
register file and three functional units: two integer
arithmetic logic unit
In computing, an arithmetic logic unit (ALU) is a Combinational logic, combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit (FPU), which operates on ...
s 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
Ethernet ( ) is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 198 ...
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
The Linux kernel is a Free and open-source software, free and open source Unix-like kernel (operating system), kernel that is used in many computer systems worldwide. The kernel was created by Linus Torvalds in 1991 and was soon adopted as the k ...
version 2.6.36 but was dropped in kernel version 4.16. A non-official LLVM back-end for Tilera exists.
