Abstract :
The RHPPC Single Board Computer (SEC) has an open architecture based on COTS standards for form factor, instruction set, operating system, backplane bus, and I/O. The RHPPC is a radiation hardened processor derived from PowerPC 603eTM technology licensed from Motorola. The RHPPC is 100% software compatible with the commercial PowerPC603eTM part allowing all the mature COTS PowerPCTM software development tools to be used with the RHPPC. The RHPPC SEC architecture has been defined in conjunction with several key users. The RHPPC has a VxWorksTM integrated operating environment consisting of startup code (SUROM), a Board Support package (BSP) and I/O drivers. This flight code is written in C using Wind River´s COTS TornadoTM software development environment. The RHPPC SEC provides enough throughput to enable on-board payload processing or can be used for spacecraft control functions. The RHPPC SEC offers 210 MIPS performance
