Embodiment Construction

[0017] In order to make the manufacture, operation method, objectives and advantages of the present invention more obvious and easy to understand, several preferred implementation modes are specifically listed below, together with the accompanying drawings, and are described in detail as follows:

[0018] figure 2 is a schematic diagram showing the hardware architecture of the handheld device according to the embodiment of the present invention. Such as figure 2 As shown, for a system with limited resources, a general interface controller can be provided to exchange data between different types of devices, instead of multiple dedicated controllers. The handheld device 200 may include a plurality of master devices (for example: master device 1, master device 2, master device n, etc.) 202[1], 202[2]~202[n] as shown in the figure, a universal interface controller 203, and multiple slave devices (for example: slave device 1, slave device 2, slave device m, etc.) 208[1], 208[2]...

Abstract

The invention discloses a general-purpose interface controller, which comprises an interface controller of a secondary device and an interface controller of a main device for interchanging data between the main device and the secondary device in an electronic device. Data and a first control signal are received and then converted into a request signal by one of automatic devices of the interface controller of the secondary device. The interface controller of the main device is used for receiving data and the request signal from the interface controller of the secondary device, converting the request signal into a second control signal cognizable by the secondary device, and transmitting data and the second control signal to at least one secondary device. The general-purpose interface controller provided by the invention has the advantage of integrating a plurality of surrounding devices of the electronic device more efficiently through the provided general interface controller of the secondary device and the interface controller of the main device; and wasted space is small.

Description

technical field [0001] The present invention relates to an electronic device with different peripheral devices, in particular to an electronic device with a general purpose interface controller (general purpose interface controller) that can provide data and control signal transmission between various peripheral devices . Background technique [0002] Most electronic devices, such as mobile phones, personal digital assistants (personal digital assistant, PDA), or global positioning system (global positioning system, GPS) navigators, etc., are usually integrated with various peripheral devices, such as liquid crystal modules (liquid crystal modules, LCM ), a memory, a camera module, and a universal serial bus (universal serial bus, USB) device, etc. Therefore, how to efficiently integrate various peripheral devices has become an important issue to improve the performance of electronic devices. [0003] figure 1 It is a schematic diagram showing various peripheral devices i...
