Tilera Corporation is a fabless semiconductor company focusing on scalable multicore embedded processor design. The company ships multiple processors, including the TILE64, TILEPro64, and the TILEPro36, TILE-Gx72, TILE-Gx36, TILE-Gx16 and TILE-Gx9.
In 1990, Anant Agarwal led a team of researchers at Massachusetts Institute of Technology to develop scalable multi-processor system built out of large numbers of single chip processors. Alewife machines integrated both shared memory and user-level message passing for inter-node communications.
In 1997, Agarwal proposed a follow-on project using a mesh technology to connect multiple cores. The follow-on project, named RAW, commenced in 1997, and was supported by DARPA/NSF's funding of tens of millions, resulting in the world's first 16-processor tiles multicore and proving the mesh and compiler technology.
Tilera was founded in October 2004, by Agarwal, Devesh Garg, and Vijay K. Aggarwal. Tilera launched its first product, the 64-core TILE64 processor, in August 2007. Tilera raised more than $100 million in venture funding from Bessemer Venture Partners, Walden International, Columbia Capital and VentureTech Alliance, with strategic investments from Broadcom, Quanta Computer and NTT. The company is headquartered in San Jose, California and operates a research and development facility in Westborough, Massachusetts, USA. It has Sales and Support Centers in Shenzhen China, Yokohama Japan and in Europe.
Tilera's primary product family is the Tile CPU. Tile is a multicore design, with the cores communicating via a new mesh architecture, called iMesh, intended to scale to hundreds of cores on a single chip. The goal is to provide a high-performance CPU, with good power efficiency, and with greater flexibility than special-purpose processors such as DSPs. In October 2009, they announced a new chip family TILE-Gx based on 40nm technology that features up to 72 cores at 1.2 GHz. Other TILE-Gx family members include 9-, 16-, 36-core variants.
Their primary markets for this new chip which launched in October 2011, include:
- Cloud computing applications such as web indexing, search engine and cache acceleration servers
- Networking equipment including intelligent routers, firewalls, network test equipment, and forensic / data-mining applications
- Multimedia applications such as videoconferencing, broadcast video servers, and edge QAM systems
- Wireless infrastructure such as 4G Node B Base Station, RNC, and Media Gateways
Tilera also provides software development tools — designated the Multicore Development Environment (MDE) — for Tile and a line of boards built around the Tile processors.
On 25 July 2011, TilePro processor was found by Facebook to be 3-times more energy-efficient than Intel's x86, based on Facebook's experiments on servers using TilePro processor and Intel's x86.
The Angstrom Project
Dr. Agarwal is leading a new MIT effort dubbed The Angstrom Project. It is one of four DARPA-funded efforts aimed at building exascale supercomputers. The goal is to design a chip with 1,000 cores.
