VIRTEX-II PRO BASED DATA PROCESSING UNIT FOR SMALL SPACEBORNE CAMERA INSTRUMENTS

摘要

Individual Data Processing Units (DPUs) are commonly used for operational control and specific data processing of scientific space instruments. To overcome the limitations of traditional rad-hard (RH) or fully commercial design approaches, we show a System-on-Chip (SoC) solution based on a state-of-the-art field programmable gate array (FPGA) with integrated hardwired processors. Although the design has low resource requirements for both, power and mass, the processing power capabilities are moderate to high. By the shown design, the availability of standard CPUs for general purpose use and programmable logic for special functions in one device allows a very effective partitioning of data processing into hardware and software. High sensor data rates in the order of up to some hundred Mbit/s for advanced sensors can be handled by this approach. Various specific handling methods against radiation induced upsets are used for an efficient design.
