This device will be an ideal companion part for next generation spaceflight processor devices, including the High-Performance Spaceflight Computing (HPSC) Chiplet. Programming the device and supporting software will be straightforward as it is based on an existing widely used ARM Cortex architecture. Possible applications of the device would be: - I/O Expander for processors or FPGAs, - Multi-communications interface / hub for processors or FPGAs, - Network bridge for processors or FPGAs, - Standalone A5 class processor with multiple communications interfaces, - Redundant processor system for implementing additional system-level lower power modes, - Redundant processor system for implementing failsafe strategy
Based on our experience marketing ARM Cortex-M based microcontrollers to the space market, we have determined that is a demand for a device like the I/O Expander Chip for the types of applications that are stated in section 10.1. This device, implemented in CMOS and radiation-hardened by HARDSIL would be an ideal companion chip to next generation spaceflight processors as well as a cost-effective alternative to solutions such as some expensive FPGAs and SPARC-based products.
