Patent attributes
An integrated circuit includes a processing engine configured to execute instructions that are synchronized using a set of events. The integrated circuit also includes a set of event registers and an age bit register. Each event in the set of events corresponds to a respective event register in the set of event registers. The age bit register includes a set of age bits, where each age bit in the age bit register corresponds to a respective event register in the set of event registers. Each age bit in the age bit register is configured to be set by an external circuit and to be cleared in response to a value change in a corresponding event register in the set of event registers. Executing the instructions by the processing engine changes a value of an event register in the set of event registers.
