An open architecture for next generation space onboard processing

An advanced, scalable, standards-based high performance computer architecture, derived from DARPA High Performance Computing research, and adapted for space on-board processing is presented. Networked multicomputing achieves supercomputing performance by combining low cost, high performance, highly integrated single chip microprocessors and high bandwidth inter-processor network fabrics. To achieve high processing efficiency, a two level multicomputer isolates the application processing resource from the communication and control layer. Here we present a two level space on-board processor architecture in which the communication and control layer of the multiprocessor has been allocated functions essential to achieve required survivability and reliability for space applications.
