摘要

UniBoard is a generic high-performance computing platform for radio astronomy, developed as a Joint ResearchActivity in the RadioNet FP7 Programme. The hardware comprises eight Altera Stratix IV Field Programmable GateArrays (FPGAs) interconnected by a high speed transceiver mesh. Each FPGA is connected to two DDR3 memorymodules and three external 10Gbps ports. In addition, a total of 128 low voltage differential input lines permitconnection to external ADC cards. The DSP capability of the board exceeds 644E9 complex multiply-accumulateoperations per second.The first production run of eight boards was distributed to partners in The Netherlands, France, Italy, UK, China andKorea in May 2011, with a further production runs completed in December 2011 and early 2012.The function of the board is determined by the firmware loaded into its FPGAs. Current applications includebeamformers, correlators, digital receivers, RFI mitigation for pulsar astronomy, and pulsar gating and search machinesThe new UniBoard based correlator for the European VLBI network (EVN) uses an FX architecture with half theresources of the board devoted to station based processing: delay and phase correction and channelization, and half to thecorrelation function. A single UniBoard can process a 64MHz band from 32 stations, 2 polarizations, sampled at 8 bit.Adding more UniBoards can expand the total bandwidth of the correlator. The design is able to process both prerecordedand real time (eVLBI) data.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
