摘要

SpaceWire is a spacecraft on-board data-handling network which connects instruments to the mass-memory, data processors and control processors, which is already in orbit or being designed into more than 100 spacecraft. SpaceFibre is a new, multi-Gbits/s, on-board network technology, which runs over both electrical and fibre-optic cables. SpaceFibre is capable of fulfilling a wide range of spacecraft on-board communications applications because of its inbuilt quality of service (QoS) and fault detection, isolation and recovery (FDIR) capabilities. The Microsemi RTG4 is a new generation radiation tolerant FPGA. It has extensive logic, memory, DSP blocks, and IO capabilities and is inherently radiation tolerant, having triple mode redundancy built in. The RTG4 has a flash configuration memory built into the device. In addition the FPGA incorporates 16 SpaceWire clock-data recovery circuits and 24 multi-Gbits/s SerDes lanes to support high-speed serial protocols like SpaceFibre. STAR-Dundee has implemented SpaceWire and SpaceFibre IP cores using the Microsemi RTG4 Development Kit. The flight proven SpaceWire IP core was initially run at over 200 Mbits/s and the SpaceFibre IP core at 2.5 Gbits/s. With a little more work it is expected to reach 300 Mbits/s and 3.125 Mbits/s respectively. The SpaceWire IP core takes around 1% of the FPGA and the SpaceFibre IP core around 3¿¿¿5% depending on the number of virtual channels supported. The use of the RTG4 with the SpaceWire and SpaceFibre IP cores provides a powerful platform for future spacecraft on-board instrument control, data-handling, and data processing. Furthermore the advanced QoS and FDIR capabilities of SpaceFibre make it suitable for a wider range of spacecraft onboard applications including integrated payload data-handling and attitude and orbit control networks and launcher applications where deterministic data delivery is required. This paper reports on the implementation and testing of the SpaceWire and SpaceFib- e IP cores in the Microsemi RTG4 FPGA.
