Duet is a dual-DSP coprocessor board which features a 4M or 5M Virtex-II Pro user reconfigurable FPGA, plus a PMC/XMC module site with JN4 and Rocket I/O connectivity to the baseboard Virtex FPGA. Unusually dense and small, Duet is packaged as a 3U cPCI board with an advanced architecture that provides superb inter-processor connectivity and direct hardware access to high-performance PMC-based external analog and communications modules, to deliver blazing performance and extreme flexibility for advanced signal capture and real-time processing applications.
The board features dual C6416 DSPs interconnected via dedicated, bidirectional, 800 MB/s FIFO links. Each processor enumerates as a 32-bit peripheral on a local 33 MHz PCI bus providing bridge-isolated access to the PMC module site from either or both processors simultaneously. A The large, Virtex II-Pro FPGA is directly accessible by each processor at rates to 260 MB/s via EMIF-B or by an installed PMC module via the dedicated 64-bit JN4 or rocketI/O interfaces. This supports a myriad of data flow scenarios, including preprocessing of PMC data by the Virtex II loic prior to post-processing by one or both DSPs. Multiple Velocia-family (Duet, Quadia and Quixote) baseboards may be assembled into an arbitrarily-large meshes using dedicated rocket I/O or SFP links or via communications via the PCI system bus.
Duet is an ideal platform for integrating high performance DSP and I/O into advanced signal processing, data acquisition and real-time applications such as telecom, RADAR, SONAR and wireless communications. Top-level performance and amazing flexibility and ease-of-use are obtained through an innovative integration of the most advanced DSP and logic devices, large independent logic chips exclusively for use by the end-user, and the best utilization of today's high-speed communication protocols.
