Based on re-engineered commercial technology, it is a licensed, rad-hard version of the IBM PowerPC 750. With nearly 10 times the performance of current rad-hard space processors, the RAD750 processor is the most
powerful radiation-hardened general-purpose microprocessor ever developed. This chip’s architecture supports the industry leading performance of >400 MIPS operating at 200 MHz. The first RAD750 flight units were launched in 2005 on Deep Impact, XSS-11, and Mars Reconnaissance Orbiter missions. Since those first flights, 28 additional RAD750 microprocessors have been launched.
