Introduction
The polyphase filterbank algorithm is a very efficient way to implement a uniformly
distributed multi-channel filterbank using a Fast Fourier Transform (FFT). This Intellectual
Property (IP) core was designed to process data in real time up to rates of 1GSPS in Virtex-4
devices. Sundance’s core is the fastest and the most efficient available in the FPGA world.
Features
• This IP core targets the following devices:
¾ Xilinx: Virtex-II TM , Virtex-II Pro TM , Spartan-3 TM and Virtex-4 TM
• Number of channels: M=2 m with m = 3 to 12 (8 to 4096 channels)
• Arithmetic type and data formats :
¾ 16-bit integer fixed point
¾ Any resolution upon request
• Configurable on the fly filter taps for each channel
• Fully functional VHDL testbench and the related Matlab functions delivered along the
FFT/IFFT core for simulation purposes and specific performance characterization.
