Patent ID: 11650651

Abstract:
A dynamic power reduction method and apparatus for use in an ultrasound system are described. In one embodiment, the ultrasound system comprises: a transducer assembly and imaging subsystem having a transmit data path having a transmitter to transmit acoustic signals and a receive data path having including signal acquisition circuitry with a receiver to receive acoustic signals representing echoes; a plurality of real-time signals indicative of status of imaging operations being performed by the transmit and receive paths; a clock generator to generate one or more clocks for use by the transmit and receive data paths; clock gating circuitry coupled to the clock generator and the transmit and receive paths and having circuits to gate clocks to at least one of the transmit and receive paths; and a clock gating controller coupled to the clock gating circuitry to control the circuits to gate or pass clock signals to at least one of the transmit and receive paths automatically in response to receipt of one or more signals from the plurality of real-time signals.
