Athena Expands Extensive FFT/DFT Processor Line

Introduces New Pipelined and Parallel Pipelined Multi-Radix FFT/DFT IP Cores

Gainesville, FL, April 29, 2013 -- The Athena Group, Inc., a leading provider of high-performance, low-power signal processing IP cores, today announced the availability of multiple new FFT/DFT processors as well as expanded capabilities within the existing product line. New introductions include low-latency FFT/DFT solutions for LTE applications, with parallel pipelined architectures that process multiple samples every clock.

The new FFT/DFT architectures significantly improve processing speed by eliminating or minimizing the switching delays when changing transform lengths. As with the original members of the Athena FFT/DFT product line, these new processors are ideal for LTE applications, with support for radices 2, 3, 4, and 5, and composite length transforms based on these radices. The parallel pipelined version accepts 2 or 4 operands per clock and produces 2 or 4 results per clock, reducing latency dramatically. To ease system integration, Athena has also introduced multiple post-scaling options for all pipelined FFT/DFT cores. Both word-based and block-based scaling options are available and enable very high dynamic range solutions when used in conjunction with Athena´s internal overflow-protected architecture.

ASIC solutions are available at frequencies of 500 MHz and more, and optimized FPGA implementations are also available for all the major FPGA families. Each design kit includes a bit-accurate C model, a simulation model and testbenches, a targeted netlist optimized for your process/library/clock frequency, and optional RTL.

“Athena has a great history of designing state-of-the-art FFT/DFT processors with the features, flexibility, and performance our customers demand,” says Stuart Audley, Director of Engineering at Athena. “The new additions to Athena´s line of FFT/DFT processors continue in this tradition, by exceeding performance and latency requirements for new communication protocols, such as LTE Advanced, while delivering the area and power efficiencies our customers have come to expect.”
Athena´s proprietary Atomic DSP™ technology enables rapid configuration and implementation of IP cores, with each delivery specifically optimized for unique performance and area requirements. Years of research and development have produced a sophisticated portfolio of Athena signal processing IP cores, with exceptional performance and efficiency in the FFT/DFT product line.
Athena´s technology scales to very high performance levels while maintaining superior efficiency, making it ideal for the most challenging applications. Whether that challenge is speed or power, applications ranging from GPS to WiFi, LTE, and even space-based reconfigurable receivers all rely upon Athena’s technology.
