Actel Corporation (NASDAQ: ACTL) 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 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 can implement the efficient Cooley-Tukey algorithm for computing discrete Fourier transforms, which delivers a hardware accelerated flexible, area efficient and fully configurable radix-2 DIT burst I/O FFT. CoreFFT utilizes both radiation-tolerant
FPGA and mathblock fabric resources and 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
