Time-Triple Modular Redundancy™ SEU Correction Technology Validated in Proton Radiation Environment

SAN DIEGO, CA - September 7, 2004 - Space Micro Inc. today announces their successful completion of proton radiation validation of its Time-Triple Modular Redundancy™ (or TTMR™) technology used in correction of single event upsets in advanced microprocessors. Space Micro completed two proton radiation test sequences at UC Davis Crocker Nuclear Laboratory, using 51 MeV protons irradiating a Texas Instrument 320C6713 digital signal processor and an Equator Technologies BSP-15 microprocessor. These radiation tests verified TTMR™ was able to detect and correct single event upsets within both microprocessors. TTMR™ combines "time" and "spatial" redundancy within a Very Long Instruction Word microprocessor or DSP to achieve its unique SEU mitigation capabilities, allowing satellite and space designers the opportunity to design with very advanced, commercial microprocessors.

"We are very pleased to have shown our new and innovative TTMR™ technology to be successful in detecting and correcting single event upsets in commercial microprocessors", said David Czajkowski, COO for Space Micro. "We believe TTMR™ provides the industry with a new and potentially revolutionary technology to advance the performance of microprocessors in the satellite industry."

Space Micro"s Proton100k™ and Proton200k™ computers incorporate its patent pending, TTMR™ technology for single event upset (SEU) correction. An additional single event functional interrupt (SEFI) mitigation technology, called Hardened Core™, is also incorporated into both computer products. Evidence of the potential of TTMR™ can be seen in the Proton100k™ and Proton200™ radiation hardened satellite products, which provide 1,200 MIPS and 4,000 MIPS (respectively) performance at 1E-4 unrecoverable upsets per day in typical satellite applications.
