Techniques are described to transmit commands to a display device. The commands can be transmitted in header byte fields of secondary data packets. The commands can be used to cause a target device to capture a frame, enter or exit self refresh mode, or reduce power use of a connection. In addition, a request to exit main link standby mode can cause the target enter training mode without explicit command to exit main link standby mode.

Aspects of the invention provide for reducing power consumption during manufacturing testing of an IC. In one embodiment, aspects of the invention include a method for reducing power consumption during a manufacturing test of an integrated circuit (IC), the method including: providing a plurality of domains, each domain associated with a clock phase; grouping, based on each domain, a first plurality of scan chains into a first test group; grouping, based on each domain, a second plurality of scan chains into a second test group, wherein the grouping of the first test group and of the second test group includes determining which domains can be tested simultaneously; and performing the manufacturing test of the IC.

A method and apparatus that controls the clock of a digital circuit, and therefore power consumption, without substantially comprising performance is provided. The apparatus may include monitoring the utilization of a First in First Out (FIFO) buffer. For example in a systems and methods according to the invention, clock speed may be reduced when the FIFO is relatively empty and increased when the FIFO is relatively full. The clock speed may be controlled by a phase locked loop, a clock divider, a clock masking device or a combination of more than one of these methods. Power reduction may also be obtained by controlling the clocking of different stages of a pipelined device. One or more aspects of the inventions may be implemented in combination with other aspects of the invention to further reduce power use.

Circuitry for reducing power consumption is described. The circuitry includes a power amplifier. The circuitry also includes a predistorter coupled to the power amplifier. The circuitry further includes a power supply coupled to the power amplifier. The circuitry additionally includes a controller coupled to the power amplifier, to the predistorter and to the power supply. The controller captures a transmit signal and a feedback signal concurrently and determines a minimum bias voltage from a set of voltages and a predistortion that enable the power amplifier to produce an amplified transmit signal in accordance with a requirement.

The data showed that India's power consumption was 110.11 BU in the corresponding month last year. The peak power demand met in April stood at 132.77 GW, almost one-fourth less than 176.81 GW in the same month a year earlier. The peak power demand met is the highest energy supply during the day across the country.
