FFT cores are optimised for FPGA
applications
CoreFFT is a novel intellectual property core generator that produces optimised fast Fourier transform cores for use with Actel's Flash- and antifuse-based families of FPGAs.
New from Actel, CoreFFT is an intellectual property (IP) core generator that produces optimised fast Fourier transform (FFT) cores for use with Actel's Flash- and antifuse-based families of FPGAs CoreFFT is designed for high-reliability applications requiring resistance to high temperature, firm-error immunity and radiation tolerance, such as radar, ground and air communications, acoustics, oil production and medical signal processing

HMI and miniature motor control daughtercards enable designers to shave months off of their design time and easily meet the most stringent power budgets.
FPGA family promises more for less
Low-power field-programmable gate arrays claim the industry's best power-, area-, logic- and feature-per-I/O ratios in a programmable device.
CoreFFT produces FPGA-optimised modules that perform FFTs to convert a signal from the time domain to the frequency domain in order to show the spectral content of the signal.
"CoreFFT represents the latest addition to Actel's DirectCore portfolio and further demonstrates Actel's commitment to the high-reliability market", said Yankin Tanurhan, Senior Director of Applications and IP Solutions at Actel.
"Fourier transforms provide a powerful analysis tool for a broad range of applications".
"CoreFFT, in conjunction with an Actel FPGA, is an excellent option for designers of high-reliability applications that also want to benefit from the features of Actel's single-chip devices, including firm-error immunity, radiation tolerance and live at power-up capabilities".
The CoreFFT RTL generator produces modules that can compute 256-, 512- or 1024-point complex forward or inverse decimation-in-time (DIT) FFTs.
The core's DIT Radix-2 implementation has been optimised for Actel devices.
The module's input and output data is represented as 32bit words comprised of 16bit real and imaginary parts.
A dual-input buffer and a single-output buffer support the input of new data samples with FFT computation, as well as the resulting output simultaneously.
In addition, CoreFFT contains all the necessary memory buffers, butterfly and control logic, as well as phase factors for the target applications.
CoreFFT has been optimised for Actel's Axcelerator, RTAX-S, ProASIC Plus and ProASIC3 FPGAs.
Other features of the new CoreFFT include: selection of unconditional or conditional block floating-point scaling; an embedded RAM-block based phase factor generator; and precise 16bit input/output data and phase factor coefficients.
Actel's new CoreFFT generator is available now.
The core is $500 for a multiple-use RTL generator.
In addition, a free evaluation version is available for download via Actel's website.
