VR,

I have the second edition of the rulph book.

section 10.4 is titled:
Radix-4 fft with RTDX using visual C++ and matlab for plotting.

The second edition of the book does not even have a discussion of frequency
domain filtering.

Some of the projects, like viterbi, have a GEL file with a slider implementation.
You could use that as an example to create your own GEL file for your project.

Victor-

Suggest to search your CCS folders for:

dsk6713.gel

this is the standard DSK 6713 board .gel file.

VR,

I just read through the section 10.4 of the book.

There was no mention, at all, of a GEL file.

Where are you seeing a mention of a GEL file for the 10.4 project?

So I removed the debug.lkf file and rebuild the project to run without any
errors.

However, in the book it is mentioned .gel file is provided on CD for project
listed in 10.4 which i do not find

vron,

I have not seen the actual file, but; given the error message...

This error almost always is cause by a recursion of 'include' files.

Most likely the C6713.cmd file is including itself
-or-
C6713.cmd is including a file that is including itself or including the
C6713.cmd file.

This is a .cmd file source code error.

First, please post to the group, not to me.

Second, when you do post, please clarify your question. I don't know what you're asking.

To get correct results, there is no particular subset of FFT required -- they all work given the same input data and
parameters. To use one or the other (in this case radix-4), there must be a application-specific reason, for example
type of DSP or hardware, format of input data, etc.

My suggestion is to split your project into two phases:

1) First make sure the Simulink model works, with no DSK board used.

2) Then go block-by-block and enable DSK board functions.

In this way, when you encounter CCS errors there will be less code involved and it should be easier to debug. You
will build up momentum and the overall project will go more smoothly.

I agree with Richard. We need to see the error first. I currently work
with 6416, and used to use 6713- NO problem at all for these two

I can post CCS errors tomorrow.I am using 3.3.1 CCS version.

Also if I want to implement this model in simulink but I am not finding
radix-4 fft block. What would be best way to implement this partiuclar
project in simulink.

V R,

Your question:
has anyone been able to run this project successfully?

The answer is 'yes'.

Perhaps it would help if you were to present the actual build errors.
Then we could give suggestions on how to fix each build errors.

A few important bits of information would also help:
--which CCS version?
--BIOS or not?
--Your compile parameters?
(I'm assuming, since you did not mention it, that the build never gets to
the
link stage due to compile errors on individual files.)
--what are the actual error messages?
(lets start with only the error messages for an individual file)
