Hi Anil,

Thanks for your post.

There is no viterbi decoder example directly available from TI and may be, you could get it from third party.

I think, Viterbi accelerator (Viterbi Co-Processor, VCP) capabilities are available on devices such as C6416 or C6455. For more details, kindly refer the below E2E posts for better understanding:

Also, you could refer the VCP2 reference guides for c645x and c648x/9x as below:

Hi Sivaraj,

Thanks for the response.

I have used the VCP and VCP2 on 6416 and 6670 platforms. But I'm currently in need of a software implementation of the same of C64x+ platform. Could you please give information about the third parties so that i can contact them.

Thanks and Regards,

Hi Sivaraj,

Thanks for the response.

It would be of great help if you let me know about the lower version board say C62x or 'xyz' that would have a viterbi software library.

I'm looking for a viterbi library with the requirements as mentioned below.

Code rate=1/2, input bits k=224, constraint length K= 9.

Thanks and Regards,

Anil Manhar
