bristol uk products coprocessors number of employees less than 10 2009 website clearspeed.com 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 . 1 its current 192 core csx700 processor was released in 2008 2 but a lack of sales has forced the company to down size 3 and it has since delisted from the london stock exchange . 4 5 the company continues to offer its products and technology . 6 contents 1 products 2 history 3 references 4 external links products edit 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 . 7 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 . 8 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 . 9 history edit in november 2003 clearspeed demonstrated the cs301 with 64 processing elements running at 200 mhz 10 and peak 25.6 fp32 gflops . 11 in june 2005 clearspeed demonstrated the csx600 with 96 processing elements running at 210 mhz capable of 40 gflops . 12 in september 2005 john gustafson joined clearspeed as cto of high performance computing . 13 in november 2005 clearspeed made its first significant sale of csx600 processors to the tokyo institute of technology using x620 advance cards . 1 in november 2006 clearspeed x620 advance cards helped place the tsubame cluster 7th in the top500 list of supercomputers . 14 the cards continue to be used in 2009 . 15 16 in september 2007 clearspeed licensed its next generation processor to bae systems for inclusion in satellite systems . 17 in february 2007 clearspeed raised 20 million in share placing on the aim market . 18 in june 2008 clearspeed released the csx700 combining two csx600 devices with a pci express x16 interface and ecc on all memories using a lower power 90 nm process . the device delivers 96 gflops for 9 watts with 192 processing elements running at 250 mhz . the device was also released on the advance e710 card at the same time . 2 in february 2009 clearspeed announced a cost cutting programme following poor financial results for 2008 . 3 in july 2009 clearspeed delisted from the london stock exchange 5
