Automated Design of Low Complexity Fir Filters

This paper considers the design of low complexity FIR filters. Complexity is reduced by constraining the filters to have integer coefficients, which can be efficiently implemented using primitive operator directed graphs (PODG). Genetic Algorithms (GAS) are used in conjunction with a heuristic graph design algorithm, to provide a solution set which represents different compromises between perfo...

Implementation of Low-complexity Fir Filters Using Difference Methods

In this paper we discuss implementation of low-complexity FIR filters using difference methods. By realizing the differences between coefficients and from them the actual coefficients, the complexity of the filter implementations can be reduced. Here two different methods are proposed for selecting the differences. Both methods can be implemented with low execution times, making it possible to ...

Design of sharp FIR bandstop filters using quadrature masking filters

A novel computationally highly e cient realization of sharp symmetrical bandstop FIR lter is proposed. The new structure is derived using the frequency-response-masking technique, where the bandedge-shaping lter is derived from half-band lter by substituting each delay of the half-band lter by M delays. The masking lters are unconventional. They are quadrature lters derived from linear combinat...

Complexity-Aware Quantization and Lightweight VLSI Implementation of FIR Filters

The coefficient values and number representations of digital FIR filters have significant impacts on the complexity of their VLSI realizations and thus on the system cost and performance. So, making a good tradeoff between implementation costs and quantization errors is essential for designing optimal FIR filters. This paper presents our complexity-aware quantization framework of FIR filters, w...

Transposed Form FIR Filters

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 digita...
