MOUNTAIN VIEW, Calif., July 19th 2010 — Actel today announced CoreFFT v4.0, an intellectual property (IP) core providing Fast Fourier Transform (FFT) capabilities to DSP solutions in high reliability, radiation-tolerant spaceflight applications. Actel’s recently qualified RTAX-DSP FPGAs (see Actel’s RTAX-DSP FPGAs Achieve MIL-STD-883 Class B Qualification) integrate radiation-tolerant math blocks with the spaceflight-proven industry-standard RTAX-S FPGA architecture. CoreFFT v4.0 uses these on-chip resources to deliver a flexible, fully configurable radix-2 decimation-in-time (DIT) burst I/O FFT for high reliability, radiation-tolerant applications.
CoreFFT v4.0 implements the efficient Cooley-Tukey algorithm for computing discrete Fourier transforms, delivering a hardware accelerated flexible, area efficient and fully configurable radix-2 DIT burst I/O FFT. CoreFFT not only utilizes both radiation-tolerant FPGA and mathblock fabric resources, but also delivers an increased upper data width limit to reduce quantization noise.
CoreFFT v4.0 Key Features:
- Highly parameterizable DirectCore RTL generator optimized for the RTAX-DSP family
- Forward and inverse complex FFT
- Transform sizes from 32 to 8,192 points
- 8 to 32 bits input/output real and imaginary data and twiddle coefficients
- Two’s complementary I/O data
- Bit-reversed or natural output order
- Selection of unconditional or conditional block floating point scaling
- Embedded RAM-block-based twiddle look up table
- Built-in memory buffers with optional extensive or minimal memory buffering configurations
- Handshake signals to facilitate easy interface to user circuitry
- CoreFFT is optimized for use in the following devices in the RTAX-DSP family:
- RTAX2000D
- RTAX4000D
