  • Static image retiling and power management method and circuit
    Patent number: 9041720
    Abstract: A circuit includes memory retiling methods which distribute image information among a plurality of memory channels producing reconfigured image information distributed among a subset of the plurality of memory channels allowing memory channels outside of the subset to be placed into a power save mode to reduce power consumption. Additional methods are disclosed for further reductions in power consumption.
    Type: Grant

  • Circuits and methods for providing adjustable power consumption
    Patent number: 8799685
    Abstract: Circuit and methods provide for adjustable power consumption using a plurality of memory controllers. In one example, a first memory controller has a first power consumption level. A second memory controller has a second power consumption level that differs from the first power consumption level. Memory controller bypass logic is connected to the first and second memory controllers and selects for a memory client at least one of the first and second memory controllers in response to a change in a power conservation condition.
