Embodiment Construction

[0039] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] like figure 2 As shown, a keyboard multiplexing management method includes a baseband processor, a coprocessor, a keyboard and an external device, the keyboard is connected to the baseband processor hardware, and the key point is that the keyboard is connected to the coprocessor hardware at the same time, and , both the baseband processor and the coprocessor can directly respond to the actions of the keyboard. The baseband processor is always the manager of the logic function of the keyboard, keeping the control of the keyboard or temporarily handing over the control of the keyboard to the coprocessor. The coprocessor After obtaining the keyboard management right from the baseband processor, it will independently and directly respond to keyboard actions until the baseband processor takes back its control over the keyboard.

Abstract

A keyboard multiplexing management system and method thereof, which includes a baseband processor, a coprocessor, a keyboard and an external device, the keyboard is connected to the baseband processor hardware, and is characterized in that the keyboard is connected to the coprocessor hardware at the same time, and the baseband Both the processor and the coprocessor can directly respond to the actions of the keyboard. The baseband processor is always the manager of the logic function of the keyboard, keeping control of the keyboard or temporarily handing over the control of the keyboard to the coprocessor. After the processor obtains the keyboard management right, it will independently and directly respond to the actions of the keyboard until the baseband processor takes back its control over the keyboard. The working system responds to the technical problem of low keyboard efficiency, and the structure is simple, easy to implement, and the method is practical.

Description

technical field [0001] The invention belongs to a system and a method for multiplexing and managing keyboards in the field of electronic technology. Background technique [0002] Most of the high-end mobile phones now almost use a traditional baseband main processor and a co-processor to implement some specific functions, such as multimedia DMB (DMB is called Digital Multimedia Broadcasting), which is in digital audio broadcasting DAB (Digital Audio Broadcasting) developed on the basis of technology. It is a new concept multimedia mobile broadcasting service that integrates communication and broadcasting. It is also called the third generation of radio broadcasting). Since in the current mobile phone hardware system, the keyboard is only directly connected to the baseband processor, not directly connected to the coprocessor, the direct connection here can be understood as a hardware connection. Its connection diagram is as follows figure 1 shown. The specific keyboard res...
