How fast can the P2 store data ?

How fast can the P2 store data from say a flash A-to-D ?

Basically just store the state of one of the ports into the HUB. Using only 1 cog.

Thanks,
Bean

    You might want to qualify how much data ? - and is the Prop master or slave ? ie does it generate the clock, or need to sync to the clock, for the data burst ?

    You can write data from a port to the hubram with the full clock speed (about 160 MHz, maybe up to 200MHz with overclocking).
    For that you need to write Quads and fill them first from the port with the Pin-Transfer hardware (XFR) which is normally used for SDRAM access.
    You can store 16 or 32bits bits of the port every clock cycle.
