Hi! all,
i m using TMS3206713 DSP. i write a programm for convolution in assembly 
language.i have checked,programm is right but it is too larg.can anybody help me to reduce this
program.

Vijay,

Can you explain a little more about what you are trying to do ?

Normally people start with C and then move to linear asm if more speed is required. Actual asm
code is a final step that should only be undertaken when the C and linear asm steps have been
proven not to work.

I'm sure TI have a convolution operation in their DSP library that you could use.

If you are doing this as an exercise, you should read spru198i.pdf

I had to check my calendar just now.  No, it's not April 1.  I have a 
great way of making money.  Can someone give me $1,000,000.00 to get 
started?

While I've picked up a lot about DSPs in the past couple of years, I'm 
definitely not fluent in reading assembly.  Normally you would start 
with something in C, see what the compiler produces, and then either 
optimize the C and look at the compiler output again, or optimize the 
assembly.  In my case I'd stick with programming in C/C++ and looking at 
the assembly output to see how efficient it looks, and then search for a 
prebuilt library that may be better optimized than I can produce.
