You could make your device actually process the data in the function that receives it. If you want that to have latency or to process the data gradually (although it sounds like you don't) you could use that function to schedule an event or events for later. Conceptually you'd be implementing an interrupt (or event, or callback, or ...) driven architecture instead of a polling architecture, but external to the device it would look the same. On top of being easier to implement, your simulation should run faster.
