Cydrome was a computer company started in 1984 in San Jose, California San Jose , California whose mission was to develop a numeric processor. The founders were David Yen , Wei Yen , Ross Towle, Arun Kumar, and Bob Rau the chief architect . In order to improve performance in a new instruction set architecture , the Cydrome processors were based on a very long instruction word VLIW containing instructions from parallel operations.

The company closed after roughly 4 years of operation in 1988. Many of the ideas in Cydrome were carried on in the Itanium architecture. The company was originally named Axiom Systems . However another company in San Diego called Axiom was founded earlier. Axiom Systems called its architecture SPARC . It sold the rights to the name but not the architecture to Sun Microsystems and used the money to hire NameLab to come up with a new company name. They came up with Cydrome from cyber and drome . Cydrome moved from an office in San Jose to a business park in Milpitas, California Milpitas on President s Day 1985. This site was used ... SIGHPC exists. Late in its history, Cydrome received an investment from Prime Computer s and OEMed the Cydra 5 through Prime. The system sold by Cydrome had white skins. The skins for the Prime OEM system was black. In the Summer of 1988 Prime was set to acquire Cydrome. At the last minute the board of Prime decided not to go through with the deal. That sealed the fate of Cydrome. The numeric processor ... in California it Cydrome ... more details
Orphan date October 2008 The Cydra 5 departmental supercomputer is the first minisupercomputer designed by Cydrome . It was completed in 1987 . At that time Cydra 5 cost from 0.5 million to 1 million ref http www.ece.rutgers.edu hsbakshi cydra 5.pdf Rutgers The Cydra 5 departmental supercomputer Cydra Inc. ref , but achieved one third to one fifth performance of supercomputers which cost around 10 million to 20 million. The Cydra 5 is a heterogeneous Central processing unit processor system. There are two types of processors functionally specialized for different components of workload . The numerical processor just work on numerical computations while the general purpose processor worked on non numerical instructions to keep the numerical processor free from that work. Possibly 2 systems were delivered. CMU at the Pittsburgh Supercomputer Center had one. Design philosophy The host processor attached processor approach was rejected because of its performance limitations.

Refimprove date July 2008 Dr. Wei Yen is a software developer and entrepreneur . He has been involved with several companies, including most recently as chairman and founder of AiLive . Dr. Yen and his brother David Yen published the paper Data Coherence Problem in a Multicache System along with King sun Fu which describes a practical cache coherence protocol. Career Wei Yen served as the Director of Software Engineering for Cydrome Inc , where he worked with his brother David, who served as the Director of Hardware Engineering. They were the major contributors to the Cydra 5 mini supercomputer. The system was a combination of a VLIW ECL based processor used for scientific applications and a multi processor system designed for a bus architecture based on their Cache Coherence protocol. Wei served as Senior Vice President of Silicon Graphics SGI . In 1996, Dr. Yen left SGI and founded TVsoft, a maker of interactive software for television setup devices. It was renamed Navio, a company that merged with Oracle s Network Computer NCI . It became liberate and then went public in July, 1999.

Multiflow Computer, Inc. , founded in April, 1984 near New Haven, Connecticut New Haven, Connecticut, USA , was a manufacturer and seller of minisupercomputer hardware and software embodying the VLIW design style. Multiflow, incorporated in Delaware , ended operations in March, 1990, after selling about 125 VLIW minisupercomputers in the United States , Europe and Japan . While Multiflow s commercial success was small and short lived, the fact of its technical success and the dissemination of its technology and people had a great effect on the future of computer science and the computer industry. Multiflow s computers were arguably the most novel ever to be broadly sold, programmed, and used as if they were normal computers other novel computers either required novel programming, or represented more incremental steps beyond existing computers . Along with Cydrome , an attached VLIW minisupercomputer company that had less commercial success, Multiflow demonstrated that the VLIW design style was practical, a conclusion surprising to many. While still controversial, VLIW has since been a force in HPTC high performance embedded systems , and has been finding slow acceptance in general purpose computing. Early history Technology roots The VLIW for Very Long Instruction Word design style was first proposed by Josh Fisher Joseph A. Josh Fisher , a Yale University computer science professor, during the period 1979 1981. VLIW was motivated by a compiler scheduling computing scheduling technique, called trace scheduling , that Fisher had developed as a graduate student at the Courant Institute of Mathematical Sciences of New York University in 1978. Trace scheduling, unlike any prior compiler technique, exposed significant quantities of instruction level parallelism ILP in ordinary computer programs, without laborious hand coding. This implied the practicality of processors for which the compiler could be relied upon to find and specify ILP. VLIW was put forward by Fisher as ... more details
