TMS320C6415: TMS320C6415

One more clarification: The MIPS requirements of an acoustical echo canceller depend on the maximum duration of all possible echoes but the typical necessary performance for one channel is 6 to 20 MIPS.

Hi,

I understood it support T1, It is also support E1?

Thanks

Hi,

We are looking for an ECHO canceler that will have PCM in and PCM out interfaces
Does TMS320C6415 have it , if not can you offer PN for this requirement?

Thanks

Hen,

Why have you chosen to look at the TMS320C6415 for this project? What features does it bring that you need, specifically?

Others may have different opinions, but I have not seen a need for PCM inputs. Depending on exactly what you want implemented, you can be creative with the McBSP lines and implement what you want in software. That might be expensive in MIPS, but perhaps you have plenty left over from your AEC implementation?

Another approach would be to move to the 66AK2G12 processor. It has better math performance on its more advanced DSP and it includes the PRUSS which can be used to bit-bang most any I/O scheme you would like.

Hi,

I see that there is 1 McBSP channel that can be connected to E1/T1 framers but we need to connect 2 E1/T1 framers how we can do that ? , for me this chip seems to be overkill don’t you have something simple ?

Thanks

Hen,

We have been trying to address your questions, but this thread does not seem to be converging very well.

Please reference the document and statement that you are referencing. Tsvetolin showed you the excerpt above that there are 3 McBSP ports. If you found alternate information, please point us to it for clarification.

You can search for exactly what you need across several TI processor families by going to the various Product Selection Guides. Start at TI.com, click Products then Processors (high-performance ARM-based or DSP-based or both) or MicroController (low power, lower cost, lower clock speed, lower complexity). On each of those pages, there will be a Products tab to click. After clicking the Products tab, you can scroll down to see the product selection filters to look through for the features or price or speed or I/O you need.

To get a recommendation or to find an appropriate device in the Product Selection Guides from above, you will need to have a list of all the requirements for both I/O and processing performance. T1 usually means a lot of channels of parallel data coming in and/or going out. Echo Cancellation can mean high/medium/low processing requirements depending on the nature of the product. You are the expert on what you want to build; we can address device questions to help.

Thanks for your answer!

Does TI supply also the code for Echo canceler?

 

Hen,

Others may have a better answer for you, but my recommendation is to do a search on TI.com for various terms like "echo canceller", "acoustic echo cancellation", and so on, without the quotes.

It may be worthwhile also to look through the available TI Designs, currently found from TI.com clicking the Applications & designs tab. A long list to look through, but you may also find some others that would apply to other products your company is working on or that you might be considering for future products.

For what it is worth, without answers to any of my questions for clarifications, I would recommend you start with the C6748 and use its LCDK6748 board to try things out.
