CPUP (Compatible Processor Upgrade Program)

CPUP was implemented by Dr. FitzHugh while employed as the Vice President for Research & Technology for CPU Technology (now part of Boeing), a small California-based business. It was an active project (funded through 2005) under the Naval Supply Systems Command’s Logistics Productivity R&D Program. It was executed under contract through the SEALEGS (Service-Life Extension of Avionics Legacy Equipment with Guaranteed System) Phase III SBIR with the Naval Air Systems Command.

CPUP provides an economic solution for obsolescence problems encountered by users of complex real-time computer systems such as those found in avionics, munitions and communications systems. Application software that operates within the systems can require an appreciable investment of time and money to design, whereas the hardware it runs on is susceptible to rapid obsolescence. For example, commercial processor technology is renewed about every 18 months, creating a host of support challenges especially as weapon system life cycles are extended past their originally designed end of-service dates.

A CPUP replacement processor (and ancillary hardware) is inserted into an existing system to increase reliability, safety and performance while safeguarding the investment in, and operability of unique application software. All CPUP designs are forward engineered to avoid patent and intellectual property issues. All information required to build models and implement designs is derived from information and documentation generally available to anyone. A functional prototype replacement has been fabricated for the AN/AYK-14 Standard Airborne Computer. The Operational Flight Program for both the EA-6B and the F/A-18 has been successfully executed on the CPUP prototype.

From the Naval Supply Systems Command: The cost of reengineering legacy software around a modern high-speed processor is prohibitive in terms of available budget. In addition the lengthy verification cycle for such a redesign is unacceptable from a readiness perspective. The Naval Supply Systems Command (NAVSUP) has invested in a unique technology through the Small Business Innovative Research (SBIR) Program, which provides a solution to computer processor obsolescence across many hardware platforms. This solution is entitled the Compatible Processor Upgrade Program.
