This paper describes the key modules for implementing a modern heterogeneous multiprocessor system for use on-board spacecraft. The objective multiprocessor system supports general purpose processor (GPP), digital signal processor (DSP), and reconfigurable computing cluster processing (RCC) modules communicating via the SpaceVPX (VITA 78) backplane standard. RapidIO data plane, SpaceWire control plane, and I2C utility plane are supported by each module type. This paper discusses the designs and the decisions that went into creating these modules as well as details on the capabilities and technical performance measures for the modules. Discussions of testing these new high performance modules is included. A sample SpaceVPX system containing power converter(s), a Space Utility Management module, each processing module type, optional switch modules plus potential daughter cards is described. Example configurations illustrate the combined performance and bandwidth improvements possible for future spacecraft missions.1
