Software and hardware for monitoring, testing, and developing communication and electronic systems on spacecrafts. Several systems are provided to monitor, test, and control a next generation SpaceCube, including a RadHard Monitor (RHM), a Mini ASTM Board, an FMC+ ASTM Board, a Mini Evaluation Board, a MEZZ and an Automated Test Suite. The RHM are FPGA IP and hardware configured to monitor COTS components. The Mini ASTM Board connects a Mini Processor Card to an ASTM for electrical testing. FMC+ ASTM Card connects FMC and FMC+ test cards to the ASTM for electrical testing. A Mini Evaluation Board supplies all necessary power to the Mini Processor card. The MEZZ is a multi-use GSE test board that is compatible with several different development platforms in the SpaceCube to allow developers to develop and test their software. The Automated Test Suite provides functional testing of an assembled SpaceCube board.

Test, development and deployment infrastructure for spacecube high-performance flight processors

A processing system including an FPGA having a dual port RAM and for use in hostile environments. The FPGA includes three portions: a C&DH portion; a first scratch pad portion receiving a first set of data, processing the first set of data, and outputting a first set of processed data to a first location of the RAM; and a second scratch pad portion receiving a second set of data identical to the first set of data, processing the second set of data in the same way that the first set of data is processed, and outputting a second set of processed data to a second location of the RAM. The C&DH portion compares the first set of processed data to the second set of processed data and, if the first set of processed data is the same as the second set of processed data, outputs one set of processed data.
