Title:
PROCESSOR AND EVENT PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/048964
Kind Code:
A1
Abstract:
Provided are a processor and an event processing method which are capable of measuring, in real time, the time it takes to return to a RUN state after executing an EVTWAIT instruction, without consuming external timer resources. This processor is provided with: a timer counter TMR which starts counting from an initial value; an event input control unit (26) which detects an event input that indicates occurrence of an event; an EVTWAIT instruction detection unit (27) which detects a wait event in response to the event input; a state control unit (30) which, in response to an EVTWAIT instruction, causes a transition from a RUN state to a WAIT state and outputs a count start signal, and which, in response to the detection of the wait event, causes a transition from the WAIT state to the RUN state and outputs a count end signal; and a TMRCAP register (23) which retrieves and holds the count value of the timer counter TMR in response to the count end signal output from the state control unit (30).
