Abstract: A system including asymmetric control of high-speed bidirectional signaling includes a slave device and a master device that is coupled to the slave device via a plurality of bidirectional data paths, for example. The master device may control data transfer between the master device and the slave device. More particularly, the master device may adaptively modify transmit characteristics subsequent to adaptively modifying receiver characteristics based upon information received from the slave device via one or more unidirectional data paths.

Abstract: In one embodiment, a system comprises a memory; a memory interface coupled to the memory; a processor unit coupled to the memory interface, a second interface coupled to the processor unit, and a graphics processing unit. The processor unit comprises at least one processor core and a display controller configured to couple to a display. The graphics processing unit is configured to render data into a frame buffer representing an image to be displayed on the display. The processor unit is configured to deactivate the second interface if the graphics processing unit is not rendering, and the display controller is configured to read the frame buffer data for display even if the second interface is deactivated.
