Abstract

An integrated circuit is provided for obtaining interrupt performance metrics. The integrated circuit includes a microprocessor executing an interrupt service routing monitoring framework that includes an interrupt handler and an application programming interface. The interrupt handler executes in response to a trigger condition and obtains timing data that includes at least one sample of a value of a timing logic according to a sampling schedule. The API exposes interrupt configuration functionality for registering the interrupt handler with a supervisory program and for configuring the interrupt handler to obtain the timing data.
