Abstract: Embodiments relate generally to a scalable, modularized mechanism which allows for storing programmable data streams on chip and provides repeatable on-demand issuances of data streams to one or more targeted instruments. In some embodiments, multiple data streams are grouped into data stream schedules to perform a series of programmable operations on demand. In these and other embodiments, data stream schedules can be reused and further grouped into data stream plans that can be executed in any order upon request or are hard-coded in a specific order.
