Sundance adds Dillon's FFT IP to SMT702 PXIe LXT FPGA

November 23, 2008 - Sundance partnered with Dillon Engineering to deliver a joint solution that makes available Dillon’s portfolio of Fast Fourier Transform (FFT) IP on the Sundance SMT702 dual ADC, PXIe embedded computing module. By marrying Dillon’s cores with Sundance leadership in modular FPGA design, developers have access to a uniquely configurable, cost effective and high performance embedded solution.

Area efficient, Dillon's FFT cores occupy fewer FPGA logic resources in terms of XtremeDSP slices and BRAMs than comparable off-the-shelf FFT cores. Dillon's IEEE-754 Floating-point FFT core sustains a rate up to 250Msps to deliver a 36 percent faster performance versus comparable cores. By offering a FFT length up to 64M points, Dillon’s core sets the industry benchmark.

The joint solution is supported by design support from the 3L Diamond multiprocessor tool suite and a bit-accurate and MATLAB compatible C/C++ model, testbench, datasets and data generators. Dillon’s FFT cores are initially available on the Sundance SMT702 module. They include pipelined for continuous processing; parallel and dual parallel for concurrent processing and extreme performance of over 25Gsps; ultralong using the SMT702s external DDR2 SDRAM for long transforms up to 64M points; parallel butterfly; mixed radix; and 2D/3D multi-dimensional FFT processing.

“Our highly parameterized cores can be quickly and easily tailored to meet the size, performance, and data processing needs of any application and any silicon target,” said Tom Dillon, president of Dillon Engineering. “This capability, coupled with the cost benefit, feature set and modular format of the SMT702, delivers a compelling embedded computing solution that is distinct in its performance and flexibility.”

The SMT702 is fitted with the fastest Xilinx Virtex-5 LX110T-3 FPGA and delivers data rates of up to 250Msps and up to 64M points IEEE-754 single precision FFT. Optimized for high-performance logic with low-power serial connectivity, the FPGA is supported by 2 banks of 64-bit 512Mb DDR2 SDRAM and dual 3GHz ADC that can be combined to deliver 6 Gsps. 8-lanes of PXI Express deliver 16Gb/s of effective bandwidth per direction and the module can plug in to any PXI Express peripheral slot or any PXI Express hybrid slot.

Dillon Engineering’s pipelined floating-point FFT uses modular Radix-2 FFT architecture to provide discrete transform on data frames or continuous data streams, with sample rates up to the maximum clock frequency. This efficient structure employs a single butterfly and single delay feedback path per rank for low localized memory usage. True IEEE-754 floating-point data is maintained throughout, supporting a large dynamic range of data without requiring complicated fixed-point analysis.

“By providing a home for Dillon’s cores on our SMT702 there is a clear path for PCIe and PXIe customers to access extreme FPGA FFT processing,” said Flemming Christensen, managing director of Sundance Multiprocessor Technology Ltd. “Their industry-leading performance metrics and compact footprint unlock system gates and logic blocks inside the FPGA to yield greater opportunity, flexibility and potential for the application designer.”

The SMT702 is immediately available with a number of different Dillon FFT IP options. Prices subject to FFT core and configuration.
