Abstract: A memory controller conveys a clock signal with command and address signals to a registered clock driver (RCD) on a memory module. A controller-side chip interface on the RCD supports both source-synchronous and filtered clocking for receipt of the command and address signals, the selection between the two clocking schemes dependent upon the noise environment impacting the clock and command/address signals. If the noise is predominantly correlated, then the chip interface is placed in a source-synchronous clocking mode. If the noise is predominantly uncorrelated, then the chip interface is placed in a filtered clocking mode that filters out uncorrelated noise from the clock signal.

Abstract: Described herein are embodiments performed by a computing device capable of having a first display and a second display. The device may also execute a windowing system. Arbitrary applications execute on the computing device. Each such application has a corresponding application window managed by the windowing system. A start-projecting request may be received from an arbitrary one of the applications, and the windowing system may respond to the start request by generating, displaying, and managing a projection window. The application may generate and display content via the projection window. Responsive to the start-projecting request, display information about the first display and the second display may be used by the windowing system to display the projection window. A stop-projecting request from the application may cause the windowing system to terminate the projection window.
