Is it possible to create an interface between Teensy 3.2 and a DSP? I realize that this is a forum for Arduino but since the Teensy 3.2 is compatible with the Arduino IDE I thought it would be appropriate to ask the question here. 

Anyway, can I create an interface between the Teensy 3.2 and a DSP, more specifically the TMS320C5534-Fixed-Point Digital Signal Processor and how could I go about it?

What I am trying to do do is capture an EEG and EoG (electrooculogram) signal, amplify it, filter the signal, use the DSP for ADC and signal processing and finally get this information from the DSP to the Teensy 3.2, which will then make a decision based on the signal obtained from the DSP.

Maybe this is a simple question but I couldn't find any answers online. I am pretty new to the world of microcontrollers. 

Thank you guys!
I would use one of the serial interfaces and connect them together that way.  If Asyinc run as fast as reliable.
