ClearSpeed

ClearSpeed Technology Ltd is a semiconductor company, formed in 2002 to develop enhanced SIMD processors for use in high-performance computing and embedded systems. Based in Bristol, UK, the company has been selling its processors since 2005.〔(Tokyo Institute of Technology Selects ClearSpeed for Sun Microsystems Supercomputer )〕 Its current 192-core CSX700 processor was released in 2008,〔(ClearSpeed Releases New Advance e710 Accelerator Board and CSX700 Processor )〕 but a lack of sales has forced the company to down size〔(ClearSpeed sees CEO resign as cost-cutting starts )〕 and it has since delisted from the London stock exchange.〔(Osborne Clarke advises ClearSpeed on tender offer )〕〔(ClearSpeed shareholder communications )〕 The company continues to offer its products and technology.〔(Petapath announces selection for two PRACE WP8 prototype installations )〕

The CSX700 processor consists of two processing arrays, each with 96 processing elements. The processing elements each contain a 32/64-bit floating point multiplier, a 32/64-bit floating point adder, 6 KB of SRAM, an integer arithmetic logic unit, and a 16-bit integer multiply–accumulate unit.〔(CSX700 specification )〕 It currently sells its CSX700 processor on a PCI Express expansion card with 2 GB of memory, called the Advance e710. The card is supplied with the ClearSpeed Software Development Kit and application libraries.〔(ClearSpeed SDK )〕
Related multi-core architectures include Ambric, PicoChip, Cell BE, Texas Memory Systems, and GPGPU stream processors such as AMD FireStream and Nvidia Tesla. ClearSpeed competes with AMD and Nvidia in the hardware acceleration market, where computationally intensive applications offload tasks to the accelerator. As of 2009, only the ClearSpeed e710 performs 64-bit arithmetic at its peak computational rate.〔(ClearSpeed Squeezes 96 GFlops Out Of 12 Watts )〕
