Connect two DSP including by XINTF

Other Parts Discussed in Thread: TMS320F28235

I want to develop a control board including two TMS320F28235 in one board. Is it possible to communicate the dsp with each other with XINTF interface?

Is there special hardware considerations?

Thanks

    The XINTF is a master interface. You cannot connect it directly to another master interface (i.e., you cannot connect to XINTFs directly together). You would have to connect via shared RAM in the middle, and design some sort of arbitration hardware and/or software protocol to guard against bus connection. This can get complicated.

    Why do you want to use XINTF? How about a serial port like SPI?
