Filed:

Dec 19, 2006

Appl. No.:

11/642320

Inventors:

Jeremy J. Lees - Beaverton OR, US
Paul S. Diefenbaugh - Portland OR, US
Pradeep Sebestian - Beaverton OR, US

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 13/12
G06F 13/38
G06F 3/00
H04R 5/00
H04B 1/00
G10H 7/00

US Classification:

710 52, 381 22, 381 23, 381119, 700 94, 715716, 84601, 84602, 84605

Abstract:

A new audio playback architecture may be used, which allows the use of much larger buffering than that used by a typical audio subsystem in a computing system to improve power efficiency of the system and at the same time allows to maintain the quality (e. g. , fidelity and responsiveness) of the audio playback. The audio controller in the new architecture may be made to report back to the host system a more accurate indication of which audio frame is being set to the audio codec than a currently available audio controller does. Additionally, the controller is capable of re-fetching previously buffered (but not yet transmitted) data. Furthermore, the controller may dynamically adjust the size of its local buffer.

International Classification:

G06F 3/038

US Classification:

345204, 3482221, 345 76

Abstract:

Apparatus, systems and methods for the synchronization of asynchronous display streams are disclosed. For example, a method is disclosed including receiving a first display data stream, receiving a second display data stream, determining a temporal offset between the first display data stream and the second display data stream, and adjusting at least one blanking interval of the second display data stream to reduce the temporal offset. Other implementations are also disclosed.

A new audio playback architecture may be used, which allows the use of much larger buffering than that used by a typical audio subsystem in a computing system to improve power efficiency of the system and at the same time allows to maintain the quality (e.g., fidelity and responsiveness) of the audio playback. The audio controller in the new architecture may be made to report back to the host system a more accurate indication of which audio frame is being set to the audio codec than a currently available audio controller does. Additionally, the controller is capable of re-fetching previously buffered (but not yet transmitted) data. Furthermore, buffers in both the audio controller and the main memory may be dynamically adjusted during playback of audio data and/or for different applications.
