US Patent:

20100083023, Apr 1, 2010

Filed:

Sep 26, 2008

Appl. No.:

12/239618

Inventors:

Nebojsa Bjegovic - Santa Clara CA, US
Vanessa Cristina Heppolette - Palo Alto CA, US

Assignee:

Apple Inc. - Cupertino CA

International Classification:

G06F 1/08

US Classification:

713400

Abstract:

A method for maintaining data and clock line synchronization, which may include a clock line that may be driven high after a clock line falling edge to mitigate a clock error. Additionally, the clock error may be mitigated by maintaining a saturated state of a device. Furthermore, a register may be connected to a microcontroller and/or a graphical processing unit to negotiate control of a switch and a bus.

International Classification:

G06F 12/0842
G06F 12/0895

Abstract:

Systems, apparatuses, and methods for dynamically partitioning a memory cache among a plurality of agents are described. A system includes a plurality of agents, a communication fabric, a memory cache, and a lower-level memory. The partitioning of the memory cache for the active data streams of the agents is dynamically adjusted to reduce memory bandwidth and increase power savings across a wide range of applications. A memory cache driver monitors activations and characteristics of the data streams of the system. When a change is detected, the memory cache driver dynamically updates the memory cache allocation policy and quotas for the agents. The quotas specify how much of the memory cache each agent is allowed to use. The updates are communicated to the memory cache controller to enforce the new policy and enforce the new quotas for the various agents accessing the memory.

International Classification:

G09G 5/00

Abstract:

Systems, methods, and apparatus to transition a display device between operating modes using a single dedicated pin of a circuit connected to the display device. The dedicated pin can receive a packet signal corresponding to an operating mode for the display device, and the circuit can thereafter cause the display device to transition into the desired operating mode in response to receiving the packet signal. The operating mode can be a low power on mode where an interface connected to the circuit is deactivated and at least some circuitry of the display device is throttled or powered off. The display device can be driven in an all black state while in the low power on mode, thereby allowing the display device to more quickly transition out of the low power on mode compared to when the display device is completely off.

International Classification:

G09G 3/20
G09G 3/00

Abstract:

A data processing system can store a long-term history of pixel luminance values in a secure memory and use those values to create burn-in compensation values that are used to mitigate burn-in effect on a display. The long-term history can be updated over time with new, accumulated pixel luminance values.
