SYSTEMS AND METHODS FOR REDUCING POWER CONSUMPTION OF A COMMUNICATION DEVICE

摘要

Generally, this disclosure describes an energy-efficient Ethernet communications approach including use of clock gating of transmit circuitry.

主权项

1. A system comprising:
circuitry, comprising an Ethernet MAC (Media Access Control), capable, when operational, to:
cause generation of a signal indicating a lower power idle power state, the lower power idle power state comprising a lower power state than an active power state;cause generation of a wake signal for a first Ethernet link partner;after a predefined period of time, cause transmission of at least one Ethernet data frame to the first link partner; the circuitry, capable, when operational, to reduce power consumed by transmit circuitry in the lower power idle state, the circuitry to reduce power consumed by the transmit circuitry to control clock gating of a clock signal of the transmit circuitry.
