Chueh Dr. Chueh has more than 30 years of experience in the computer industry, covering fields from mainframes to mini-computers to workstations to microprocessors. His professional career in computer spans from research to teaching, from systems architecture to product development and from start-up to running a business. Dr. Chueh is President of Teton Systems, Inc., an international computer programming, and software service company. From 1993 to 1997, Dr. Chueh was President of Fundamental Software, Inc. Fundamental Software's main product, OPEN/370, emulates IBM S/370 and S/390 CPU and I/O Architecture on Intel processors and SCSI disks. With Open/370, a Pentium Server can run IBM mainframe O/S and applications without modification. Dr. Chueh founded Pacific Technology Associates, Inc. in 1989 with venture capital funding to development processor chips. The company developed a RISC floating-point co-processor chip and a single cache system VLSI. The company merged to Austek Microsystems in 1992. Priori to the funding of Pacific Technology Associates, from 1986 to 1989, Dr. Chueh was Director of Advanced Product Development with Fujitsu Microelectronics, Inc. Starting from a newly formed group of few engineers, Dr. Chueh built an effective VLSI design team with marketing and support organization of more than 70 professionals with three product lines: LAN, SPARC processor and DSP chips. Starting from joint SPARC development, Sun Microsystems and Fujitsu became major business partners in workstations. Some highlights of Dr. Chueh's computer career include: Researched in programming languages and digital technology. As a research scientist with Bell Labs, Dr. Chueh developed a new programming language for large communication system development. He has also taught logic design and programming techniques at UC Berkeley, UC San Diego, and National Taiwan University. Architected a major computer product lines. Dr. Chueh was a computer architect with Control Data Corporation from 1973 to 1977. During that four years, he had major responsibility for the systems architecture of Control Data's new computer line – the CYBER 180. Control Data made worldwide shipments of CYBER 180 computers throughout the 1980's, with models ranging from mini-computers to mainframe systems to super-computers. Developed a mainframe computer from concept to completion. Dr. Chueh was Director of Engineering with National Advanced Systems from 1977 to 1980. Starting from a proposal, he planned an IBM 3033 compatible mainframe project, recruited the staff, set up the organization, led and managed a team of 100 plus engineers to develop the mainframe computer system. Architected multi-processing (MP) cache systems, with both hardware protocol (for MASCOR/132) and software protocol (for CYBER 180) to ensure data consistency. Invented a Virtual Address Translations Mechanism and a Key-Lock Protection Structure, both patents granted. Dr. Chueh led a US consultant group to support Taiwan ITRI-ERSO's MP Super-mini computer research project. A prototype of the project was demonstrated at San Francisco International Computer Conference in August 1989. Dr. Chueh was also a lead consultant on 8000 Series Mainframe Development Project with North China Institute of Computing Technology of Beijing, China. The Institute, founded in 1958, is the most established computer organization in China. Dr. Chueh obtained his Ph.D. in Electrical Engineer from University of Pennsylvania (Moore School).
