Speed on ports

Dear contributors,
assumming a fast 16bit DAC with parallel 16bit interface connected to the P2, I wonder what is the maximum possible number of samples per second to be sent to a port. For sake of simplicity, let us assume 200MHz system clock.
Thanks a lot.

Using the streamer that would be 200MHz.

This is fascinating ! And how about a programmatic way using a cog without the use of a streamer ? Thanks a lot.

~100 MHz, using an unrolled loop (P2 is 2 cycles per instruction)
