Other Parts Discussed in Thread: TMS320C6678

Hello,

I'm using Tms320c6678 DSP along with CCSv5 to run one of my application specific programs.

Query 1)

The code I've written demands IFFT computation hence I've a separate project that uses the inbuilt IFFT. I want to know if I can call this IFFT project from my main project without actually merging them (copying files of one project to another) .

Query 2)

The execution time taken by the IFFT double precision program to compute N=8192 point IFFT is 44 ms. Is there any way I can reduce the number of clock cycles and hence the time.

Thanks in advance.

Hi,

1 - I think that you can do that only if you generate a lib from your ifft project nad link it in the other project

2 - Are you using TI's DSPLIB? It seems to have a faster IFFT function.

Hi,

Answer 1:

Without merging means, you shall generate the library from first project and link the same with second application.

Answer 2:

Please try optimizing the code, that may help you to reduce the cycle and time.

Thank you for your immediate reply, Johannes.

Yes I'm using TI's DSPLIB for IFFT calculation. Since I'm using it in Telecommunication field for real time operation I want very high computation speed. I'm trying to achieve <0.5ms. Can you suggest me any ways I can achieve such high computation speed?

Thanks in advance.

Hello Rajasekaran,

Thank you for your immediate reply. I appreciate your spontaneous support.

I'm building the project according to the link - http://processors.wiki.ti.com/index.php/Creating_Library_for_MSP430_Project_using_CCS_v5

According to the above link, step1 says that the "Output type" should be "Static Library" while building the library.

I want to make TI's DSPLIB - IFFT program as my "Static Library Project". The challenge I'm facing is that the inbuilt program doesn't let me change the "Output type" to "Static Library". It's "Output type" is "Executable" by default and I cannot change it.
So how do I go about making the inbuilt IFFT project as my Library Project?

Thanks in advance.

Hi,

Recreate your project and when you're creating it (on first screen where there's name, device type...) choose the output to be static library.
