Re: Digital filter on a FPGA

Hi,

In addition to using one of the core generator tools listed in the above
reply, you could design your own filter. If you choose to do this, an
excellent resource would be Ray Andraka's web site:
www.andraka.com, he has a large number of papers and various documents on the topic. A couple of good terms to look up are:
DA (distributed arithmetic) algorithm, MAC (multiply-accumulate) based
digital filters, RAG (reduced adder graph) algorithm.

Hope that helps.

Hello sajeev_antony

Maybe book "Digital Signal Processing with Field Programmable Gate Arrays" by Meyer-Baese will help you.

CH3-FIR digital filters
Digital Filters
Designing FIR filters
Constant Coefficien FIR Design
Exercises

CH4 - IIR digital filters
IIR Theory
IIR Coefficient Computation
IIR Filter Implementation
Fast IIR Filter
Exercises

Exercices in VHDL and Verilog

Check the MCUatm in UsersFiles/mhmhmh/DSPwithFPGA

Take care

Also @ltera has very good application note regarding filter design.

Does anyone would tell me where to find the examples of filter design of Altera? Is there pdf files available?
