Embodiment Construction

[0026] At first, explain the core of the present invention: adopt bus connection mode to realize high-speed communication and expansion between multiprocessor CPUs in dual-mode and multi-mode mobile phones, the following takes Intel's PXA27x processor and USB bus as an example to specifically describe the present invention:

[0027] The Intel PXA27x processor is used as a dedicated application processor, while other wireless baseband processors are dedicated to wireless services. They are connected to each other through a USB bus, wherein the application processor acts as a USB host, and each wireless baseband processor acts as a USB client. As for the USB bus that can support 127 USB devices, this number will fully guarantee the real flexible implementation of multi-mode mobile phones without increasing the communication connection, as long as the wireless baseband processor that needs to be expanded is connected to the USB bus. . It should be noted that the wireless baseban...

Abstract

The invention relates to one kind of multi-model mobile telephone. It includes antenna, the radio frequency module, the wireless baseband and the applied processor (1). Its characteristic is that it has over two wireless baseband processors. Among them, at least one wireless baseband (21) and one applied processor (1) are connected by tandem bus (3) Merits of the multi-model mobile telephone compared with now available mobile telephone are as follows: (1) It retrenches the required pins in the applied processor. (2) It is convienient in expanding, adding or replacing of the wireless base-band processor.(3)The transmission rate can reach 12 Mbps according to the USB bus. Other form of bus may be choosen to realize the mobile telephone frame.(4) According to the USB bus used in the example, data can be transmitted on the dummy bus at the same time. It saves the code control and cuts down the unnecessary use of bandwidth.

Description

technical field [0001] The invention relates to a mobile communication terminal, in particular to a multi-mode mobile phone with a multi-processor structure. Background technique [0002] With the increasingly higher requirements for smart and multimedia mobile phones, the functions of processors in mobile phones are also required to be more and more powerful. At the same time, in order to realize that one phone can be used in multiple networks, people put forward the demand for multi-mode mobile phones. In the development of multi-mode mobile phones, there is less or less correlation between the development of the application side and the development of the wireless side, that is, so that the software on the same application side can match more types of mobile phone wireless communications, such as GSM, CDMA, WCDMA, TD -SCDMA, etc. Dual-processor and multi-processor mobile phone architectures are becoming more and more popular in the design of mobile phones. But here the ...
