Abstract :
The requirements for this processor were established using the experience of the hardware and software designers in the APL Space Department. The use of commercial hardware and software products, combined with an error- and fault-tolerant architecture, resulted in a low-cost design without adversely affecting overall reliability. The processor´s architecture and mechanical design, and hardware and software test and validation methods are described
