AI Technical Summary

Problems solved by technology

This is important because, for example, when the host processor is running at high speeds, noise, glitches, and / or delays in the control signals from the host processor to the multimedia accelerator can cause spurious bus cycles and / or other operational errors
These errors may degrade the quality of data, video and / or audio, etc. produced by this multimedia accelerator

Embodiment Construction

[0071] Some embodiments of the invention relate to methods and systems for input / output (I / O) pads in mobile multimedia processors. Input, output and / or bidirectional pads in the master bus interface and / or slave bus interface are configured to provide bypass capability when the mobile multimedia processor is powered off or in sleep mode. This pad can be used to provide the ability to raise and lower potential. The potential up and down potential capabilities are dynamically programmable. The approach provides a flexible architecture for high-speed bypass operation between the host processor and peripheral devices through the mobile multimedia processor.

[0072] Figure 1A is a schematic block diagram of a mobile multimedia system according to an embodiment of the present invention. refer to Figure 1A , the mobile multimedia system 105 includes a mobile multimedia device 105a, a TV 101h, a personal computer 101k, an integrated camera 101m, an external memory 101n, and an i...

Abstract

In a multimedia system, a method and system for input / output pads in a mobile multimedia processor are provided. Input, output, and / or bidirectional pads in a host bus interface and / or a slave bus interface may be configured to provide bypass capabilities when a mobile multimedia processor is powered down or hibernating. The pads may be adapted to provide pull-up and pull-down capabilities. The pull-up and pull-down capabilities may be dynamically programmed.

Description

technical field [0001] The present invention relates to the processing of multimedia information, more specifically, to a method and system for moving an input / output area (pad, or unit) in a multimedia processor. Background technique [0002] Mobile communication has changed the way people communicate, and mobile phones have changed from a luxury item to a necessity in daily life. Now, the use of mobile phones is a social trend, not limited by geography or technology. Although the voice connection fulfills the basic needs of communication, and the mobile voice connection continues to further penetrate into various fields of daily life, the use of the mobile Internet and various integrated mobile multimedia applications will trigger the next revolution in mobile communication. [0003] 3rd and / or intermediate generations, known as 3G and 2.5G respectively, such as cellular networks that provide multiple high-speed access technologies and mobile phones specifically designed ...
