Dynamic triggering and sampling engine (DTSE) for low-latency and cost effective control systems

摘要

A Dynamic Triggering and Sample Engine (DTSE) that detects a first trigger received on a trigger input terminal that triggers a series of analog-to-digital conversions to be completed by an analog-to-digital converter circuit. The DTSE then determines a first sequence configuration stored in a sequence configuration table that is associated with the first trigger, causes a first analog-to-digital conversion to be performed using the first sequence configuration; causes a first analog-to-digital conversion result value to be stored in a sequence result table; and outputs an interrupt to a processor indicating that the first analog-to-digital conversion result value is available in the sequence result table. The interrupt is output from the DTSE before all remaining analog-to-digital conversions in the series are completed. In response to receiving the interrupt, the processor reads the analog-to-digital result value from the sequence result table via a bus.
