Researchers at CPU Tech, a privately held California-based company, are developing a core processing architecture that will make it possible to upgrade high-end embedded electronic systems while retaining the value of time-tested application software and development tools. The owners of high-end embedded systems such as those found in avionics, weapons controls and other complex electronic devices are faced with a continuing problem of obsolescence.

Processors and other electronic components have a life cycle as short as 18 months while a modern airliner, for example, has a projected life of at least 40 years. Replacing a processor can mean rewriting an entire software program at costs ranging into the hundreds of millions of dollars. The development program at CPU Tech will provide an innovative solution to electronic obsolescence problems in the form of a system-on-a-chip that will be fully compatible with a legacy processor, running the proven software without changes, while providing greatly enhanced performance as well as access to new higher order languages and commercial off-the-shelf software tools.

This research effort was funded through the Small Business Innovation Research Initiative program with a Phase II contract administered by ONR. It is also part of the Navy's Dual Use Science and Technology Program.
