CENTRALIZED POWER METER AND CENTRALIZED POWER CALCULATION METHOD

摘要

The present disclosure provides a centralized power meter for a signal processing circuit, comprising: M sample buffers, each configured to buffer samples respectively from at least one of N sources, and trigger a request for power calculation of the buffered samples in response to the buffered samples, the request having a corresponding priority; a switch, configured to route the requests from the M sample buffers to one or more power calculation cores; the one or more power calculation cores, each configured to retrieve the samples from the sample buffer in an order of their corresponding priorities, in response to the routed requests, and to perform power calculation of the retrieved samples, wherein N and M are integers no less than 1, and N is no less than M. The present disclosure further provides a centralized power calculation method.
