snrao,

Here are a few questions that must be answered before a complete solution can be suggested...

How much data are you talking about? Bytes, Kbytes, or MBytes?

How many uC's will need this data?

How fast do the uC's need to obtain the whole set of data?

Do all the uC's need the data at the same time, or can the delivery be staggered?

Is the information to be delivered to the alternate uC's, or is each uC to get the information as it feels it needs?

Do all the alternate uC's need the exact same information?

Is there any locking mechanism needed to prevent coherency problems? That is, is there a problem if the main uC updates information at the same time as when an alternate uC is loading its information--causing the alternate uC to have some, but not all, of some new information.

How close are the other uC's? On the same circuit board (inches, or feet?)

Does all the data need to be perfect? That is, is loosy information acceptable (like in multimedia.)

People can give more specific solutions when more details of the problem are stated.
