Abstract
Implementations related to systems, devices, and methods that make use of a master slave arrangement are described. In one implementation, a method of reducing overall power consumption in a master-slave system includes generating a clock signal in a master device having a first power consumption rate, transmitting the clock signal from the master device to a slave device having a second power consumption rate, the first power consumption rate is lower than the second power consumption rate, sampling data receive by the slave device, the data being provided by the master device, generating phase error information of the clock signal in the slave device, transmitting the phase error information from the slave device to the master device, and adjusting the clock signal in response to the phase error information.
Claims21
A method, comprising:
- generating a clock signal in a master device having a first power consumption rate;
- transmitting the clock signal from the master device to a slave device having a second power consumption rate, wherein the first power consumption rate is lower than the second power consumption rate;
- sampling data received by the slave device, the data being provided by the master device and an antenna associated with the master device;
- generating first phase error information of the clock signal in the master device;
- generating second phase error information in the slave device;
- transmitting the second phase error information from the slave device to the master device;
- and
- adjusting the clock signal in response to the generated first and second phase error information,
- wherein the first phase error information of the clock signal in the master device is based on phase error information generated locally in the master device, and the second phase error information is based on phase error information generated locally in the slave device.
A system comprising:
- one or more antennas to transmit and receive wireless signals via one or more wireless networks;
- a master device configured to generate a clock signal;
- a plurality of phase generators incorporated in the master device, at least one of the phase generators to provide control of control data received by the master device and at least another one of the phase generators to provide control of control data transmitted by the master device;
- and
- a slave device coupled to the master device and configured to receive the clock signal, the clock signal to control data behavior corresponding to the wireless signals and associated with the master device and the slave device.
A system comprising:
- one or more antennas to transmit and receive wireless signals via one or more wireless networks;
- a slave device;
- a master device to couple to the slave device, the master device being more power efficient than the slave device;
- a plurality of phase generators incorporated in the master device, at least one of the phase generators to provide control of control data received by the master device and at least another one of the phase generators to provide control of control data transmitted by the master device;
- and
- a clock generating unit incorporated in the master device to generate a clock signal, the clock signal to control data behavior corresponding to the wireless signals and associated with the master device and the slave device.
