APPARATUSES AND METHODS FOR GENERATING AND TRACING EVENT CODES

摘要

Apparatuses and methods implemented therein are disclosed for generating event codes and time stamped events from the generated event codes. In one embodiment the apparatus comprises a register, a counter, a timestamp fraction generator and an event code generator. The register is configured to receive a one of a set of asynchronous events. The counter is configured to receive a clock signal and generate periodic events of a configurable periodicity. The timestamp fraction generator is coupled to the register and generates a timestamp fraction in response to receiving an asynchronous event by obtaining a count from the counter at substantially the same time that the event is received. Finally, the event code generator generates an event code from the timestamp fraction and an identifier corresponding to the event.

1. An apparatus comprising:
a register configured to receive a one of a set of asynchronous events; a counter configured to receive a clock signal and generate periodic events of a configurable periodicity; a timestamp fraction generator coupled to the register and configured to generate a timestamp fraction in response to the one of the set of events being received by the register, wherein generating the timestamp fraction comprising obtaining a count from the counter at substantially a same time the one of the set of events is received; and an event code generator configured to receive the timestamp fraction and the one of the set of events and generate an event code comprising at least the timestamp fraction and an identifier corresponding to the one of the set of events.
