Product Obsolete / Under Obsolescence

This application note describes a high-speed, reconfigurable, full-precision Transposed Form FIR filter design implemented in the VirtexTM and Virtex-II series and SpartanTM-II family of FPGAs. The VHDL reference design provided with this application note is easily modified to change filter parameters including coefficients and the number of taps. By illustrating a design methodology for digital filters, the advantages of using FPGAs for digital signal processing applications (DSP) are emphasized. The Core Generator tool provides a preoptimized alternative solution to this reference design (Core Generator Tool).
