Synchronization of Data from multiple peripherals

Hi,

I am designing an embedded SW with multiple peripherals.

I have data from multiple(say 3 to 4) peripherals at different instances. I need to find the instance at which i have the data from all the peripherals and store that data in the SW. Remaining data is to be discarded.

How to find out the synchronized records from multiple peripherals?


Thanks,
SaiRam
