AIF for inter-DSP communications between TMS320C6474DSPs

Other Parts Discussed in Thread: TMS320C6474

hello,

I'm a new member of TMS320C6474 dsp user. Now i want to use AIF to achieve inter-DSP communication. i find one example about inter-dsp communication on TCI6487. But it can not run on TMS320C6474EVM. I have done some changes. So can you provide me one example about inter-dsp communication on TMS320C6474EVM? thank you very much!

Best regards!

ziteng xue,

Most software that runs on the TCI6487 runs on the C6474. What issue did you have with running that code on the C6474 EVM?

In my opinion, the SRIO is a much better way to do inter-DSP communication. It is designed for error tolerance and will run at the high speeds that you need. Please go to TI.com and search for DIOLib to get information on the DirectIO Library for SRIO communication.

You can also go to TI.com and do a search for IACLib. IACLib stands for Inter-DSP AIF Communication Library and was created for what you want to do. There are engineering issues, in my opinion, that can be involved with using AIF for general inter-DSP communication. You must be an expert on the AIF standards, the SERDES standard, and the AIF peripheral to fully understand the issues involved. I am not that expert, but I have dealt with customer issues enough to recommend using SRIO instead.

Regards,
RandyP
