Embodiment Construction

[0015] The present invention provides a mobile phone based on an application processor architecture. The main design principle of the mobile phone is that the current mobile phone baseband processors all support an external boot mode, or a mode called UARTBOOT or USB BOOT. This mode is used when there is no program or the program is destroyed in the baseband FLASH. The usual practice is that in this mode, the baseband processor will execute a specific internal program. We may download a pre-written program to RAM through the baseband UART or USB interface, and then jump to RAM to run the program just now. The downloaded program, this program implements a specific communication protocol, and downloads data to FLASH through UART or USB.

[0016] Please refer to Fig. 3, which is a structural representation of the present invention. As shown in the figure: it includes a communication module and an application module, wherein: the communication module includes a baseband processor...

Abstract

The invention provides a mobile phone which is based on a processor structure application. The invention is mainly characterized in that the invention implements the functions which are completely the same with those of the mobile phone in which the processor structure is applied, achieves the starting skillfully by adopting the external starting mode of the baseband processor of the mobile phone through a baseband processor which is controlled by the application processor, thus abolishing the FLASH which is externally connected with the original baseband processor and used for storing programs and other data. Therefore, the invention remains the flexibility and succession of the software of the mobile phone in which the processor structure is applied, reduces the cost of the whole machine at the same time, and has important and practical significance.

Description

technical field [0001] The invention relates to a processor framework of a mobile communication terminal in the field of mobile communication, in particular to a mobile phone based on an application processor framework. Background technique [0002] Currently, mobile phones are widely used. In high-end mobile phones, because there are many applications and various applications have higher and higher requirements on the CPU of the mobile phone, many mobile phones adopt the architecture based on the application processor, as shown in Figure 1. This architecture includes a communication module and an application module, wherein: the communication module also includes a baseband processor and a radio frequency part, the baseband processor is respectively connected to RAM and FLASH, and the radio frequency part is connected to an antenna. The communication module is mainly responsible for the interaction between the mobile phone and the base station, protocol processing, etc., a...
