Atomic™ Fast Fourier Transform (FFT)
High Performance FFTsProduct Brief (PDF)
Athena delivers high-performance fast Fourier transform (FFT) cores, ready to use for your SoC application. When your advanced communications or signal processing SoC requires dedicated FFT performance, turn to Athena’s Atomic FFT family. Atomic FFT blocks enable your application to realize the power, performance, and area advantages of Athena’s arithmetic technology in your FFT intensive application, and benefit from Athena’s experience delivering extreme FFT performance.
All Atomic FFT cores can perform both forward and inverse transforms with run-time programmable scaling and transform lengths and have flow control. Data precision, maximum transform length, and performance are user-defined implementation parameters. Atomic FFT cores are available with standard radix 2/4 lengths, and optional multi-radix (e.g., 2, 3, 4, 5) lengths. Optional features such as hardwired or run-time programmable windowing are also available.
