摘要：A method and apparatus of implementing protocol state machines thatconserve energy on energy conscious devices is disclosed. Under this method, most of
the energy consuming protocol state machine context invocations or operations areaggregated in time and are scheduled at regular intervals. Such an aggregation leads tomany contexts executing concurrently in a burst prior to entering a dormant state. Thus,resource usage can reach a predictable rate pattern of idle and active cycles. With such apattern, it is possible to take advantage of the energy saving features of processors bydownshifting the processor clock speed and use of other resources such as peripheralsand buses. The intervals are configured to achieve a tradeoff between timely executionand energy consumption. The aggregation operates across two dimensions, namely,multiple instances of a protocol state machine and multiple layers of protocols in alayered architecture.
