FFT implementation in Xilinx Spartan 3 started kit

You are not completely new to FPGA, that was yesterday when you came with the same question, ... A good starting point is google.com, my advice is to try something less complex and after you became familiar with the flow .... one step at a time.

Well,

This is where I would start.

If you are familiar with hardware architecture in terms of what performance you need and how fast or parallel processing required (no VHDL needed!), you may choose one mathematically familiar implementation, among several FFT implementations, you can image the architecture in terms of multipliers && accumulators && registers (let's call it microarchitecture of your design).

One you have done that, the rest is piece of cake, really. Study VHDL, do some minor projects for a few days and then you would be able to estimate your performance better than anybody in this newsgroup.

There is a way to have FFT as a core / reference, but i would not recommend this, if the goal is to study FPGAs.

Hope this helps.

Thank you Vladislav !!! My objective is to study both FPGA and computer architecture. I have prelimnary knowledge about architecture and I am trying to design simple 4-bit ALU /CPU using VHDL. I think i have virually completed it. As a student I am in process of learing. I want to know more on FPGA, Please suggest me where to start learning and also let me know your recommendation.

What can I say?

When I just joined the industry, there was a nice time where the university did not really teach FPGAs, so I had to learn about them in the industry. That is why I really cannot recommend you any book or something like this... Learn as much as you can and use the newsgroup, this is very educative... :) no kidding.

I have found a couple of books to be very good in learning VHDL and FPGA architecture, in general:

1. "VHDL Programming by Example" by Douglas L. Perry
2. "Circuit Design with VHDL" by Volnei A. Pedroni

The former is a very good introduction to VHDL. It has a good referenece section in the back for later use, also. The latter is a more circuits oriented approach using VHDL. This concentrates more on circuit structures.

Check the titles at Amazon or your favorite book outlet to get more detail on these and other books on the subject.

Hope this helps.

Thank you DAVE Yeah I am following this book "VHDL Programming by Example" by Douglas L. Perry

Code up the examples on this website for good VHDL practice
