Improvements over existing data collection interfaces disclosed herein include, among other things, additional logic blocks (and associated timers, state machines, and registers) to off-load data collection and data processing prior to waking a microprocessor from a sleep mode. For example, an improved data collection interface collects a predetermined number of sensor values from a sensor while maintaining active a single communication session with the sensor over a pin of the interface. The microprocessor remains in the sleep mode for an entire duration of the single communication session. The data collection interface can reduce the likelihood of false starts of the microprocessor by using the logic blocks to verify that data meet preconditions prior to interrupting the microprocessor. The data collection interface can reduce the overall power consumption of a chip in which the microprocessor is integrated by a factor of at least about 2&#xd7; (i.e., 50% reduction in power consumption).

Data communication interface for processing data in low power systems

Data-transfer transactions in the read and write directions may be balanced by taking snapshots of the transactions stored in a buffer, and executing transactions in the same direction back-to-back for each snapshot.

Efficient scheduling of read and write transactions in dynamic memory controllers

Data-transfer transactions from multiple masters may be balanced by taking snapshots of the transactions stored in a buffer, and executing transactions from each master back-to-back.
