  • Floating Point FFT/IFFT IP Core
    • Worlds fastest and most flexible Floating Point FFT IP Core
    • Ultra high performance (> 1GSPS possible)
    • Custom precision, any exponent and mantissa width
    • Clock speeds over 200 MHz in Virtex II Pro 
  • 128-Point FFT/IFFT IP Core
    • The FFT4T core implements a 128 point complex FFT and IFFT over 12 data streams in hardware. It runs at the clock frequency four times higher than the insput sampling frequency.
    • FFT4T core is a specialized FFT/IFFT processor intended for a situation where an RF signal is recieved over multiple channels in parallel and its filtering is to be performed in the frequency domain. The core fits nicely into, for example, a multichannel GPS system.

  • Ultra High Speed FFT/IFFT processor
    • Highly pre-synthesis design configurability with detailed generic/parameter values, in order to meet desired implementation trade-offs.
  • DVB-T2 Demodulator and LDPC/ BCH Decoder
    • DVB-T2 EN302 755 V1.2.1, Rev.9 compliant  
    • Supports IF input  
    • Single input – Single output (SISO)  
    • Sampling frequency offset (SFO) tracking and compensation  
    • Carrier frequency offset (CFO) detection and correction  
  • ASIP-2 Programmable Filter Engine
    • Platform to design Application Specific Instruction Set Processors (ASIPs).
    • Ideal for supporting multi-standard systems.
    • Supports a wide range of complex DSP functions
    • The ASIP2 performs Fast Fourier Transform (FFT) to convert time domain signals to frequency domain signals for further processing. It supports FFT sizes from 4 to 8K.
