Abstract: A memory device loops back control information from one interface to another interface to facilitate sharing of the memory device by multiple devices. In some aspects, a memory controller sends control and address information to one interface of a memory device when accessing the memory device. The memory device may then loop back this control and address information to another interface that is used by another memory controller to access the memory device. The other memory controller may then use this information to determine how to access the memory device. In some aspects a memory device loops back arbitration information from one interface to another interface thereby enabling controller devices that are coupled to the memory device to control (e.g., schedule) accesses of the memory device.

Abstract: According to one embodiment of the present invention, a method of power management for a flat panel display is disclosed. The method includes: receiving image data; determining a segment mode for the received image data; selecting a portion of the received image data corresponding to the determined segment mode; accumulating a value of the selected portion of the received image data; comparing the accumulated value to a threshold value; and generating an interrupt signal if the accumulated value exceeds the threshold value.

Abstract: An apparatus includes at least two circuits having interfaces, for transmitting and receiving bus formatted messages and a port coupled to receive messages from the interfaces. The port broadcasts a first received message that is not destined for one of the circuits to the bus. The port blocks broadcast of a second received message that is destined for one of the circuits to the bus.
