Connect bits streams at 13Mhz to XCORE

Technical discussions around xCORE processors (e.g. General Purpose (L/G), xCORE-USB, xCORE-Analog, xCORE-XA).

Connect bits streams at 13Mhz to XCORE

Postby michcfr » Tue Jan 24, 2017 6:14 pm

Hello,
I have a board which have 8 x bit streams. Each bit stream has its own associated independent bit clock. So I have: 8 x 2pins (one for the bit stream, one for its associated bit clock). Each bit clock is at 13Mhz.

I would like to connect these streams to a XCORE processor for further processing. Is it feasible?
If yes, how to organize the hardware model: pin/core, timers and communication fabric?

Thx,
Michel

Michel,

Have a look at these two pages, they should cover what you need:

Thanks,

Hi

Thank you for your reply and help.
What is the maximum GPIO speed on the XS1 and for on the X200. Thx

Hi,

You can find details on the IO speed in the relevant datasheets.

thanks,

Hello,
Thank you.
Up to how many bit streams of 13Mhz each a X200's xcore logical core can support? Thx

Regards
Michel
