Mobile phone module based on FPGA architecture and method for connecting mobile phone module with mobile phone

Abstract

The invention discloses a mobile phone module based on an FPGA architecture and a connection method of the mobile phone module and a mobile phone. The mobile phone module comprises an FPGA module, theFPGA module is connected with a plurality of functional modules through an I / O interface. The FPGA module is in communication connection with the CPU of a mobile phone through an SPI interface. The expansion of the peripheral function module of the mobile phone is realized; the FGPA has multiple I / O ports which can be flexibly configured, the I / O ports of the FPGA module can be used for simulating various conventional interfaces and can be connected with various peripheral modules, the functions of the additional modules of the mobile phone are greatly expanded, and the interfaces between themodules and the mobile phone are very simple, so that the mobile phone can support more functions. The problem that an existing mobile phone module communicates with a mobile phone through the CPU, and due to the fact that peripheral interfaces of the CPU are limited, functional modules are difficult to expand is solved. When the function module is updated, only software and hardware of the mobile phone module need to be upgraded, and the mobile phone only needs to be upgraded, so that the on-off period of the mobile phone is greatly shortened, the debugging difficulty and development time ofnew functions and new peripheral equipment of the mobile phone are reduced, and the development cost is saved.

Description

technical field [0001] The invention relates to communication equipment, in particular to a mobile phone module based on FPGA architecture and a connection method with the mobile phone. Background technique [0002] Now that the battery capacity of mobile phones is getting larger and more functional requirements are increasing, the layout space on the motherboard is becoming more and more tight. Especially under the impact of full screen, notch screen, and dual front camera, the antenna forbidden zone on the forehead of the mobile phone is getting smaller and smaller, and the WIFI / BT / GPS antenna and hierarchical antenna are increasingly interfered by surrounding devices. It is a good way to solve this problem by moving more and less commonly used modules out of the mobile phone body and putting them on additional mobile phone modules. The existing supporting modules of mobile phones are basically single functional modules. Each module has only one or two functions, such as...
