Abstract

The invention relates to a GPIO control system utilizing dual CPUs of RIL. In the prior art, even for the system utilizing dual CPUs, a device is arranged on a main CPU and a controlled CPU is only purely used as a modem, and thus the defect of insufficient of the GPIO pins for dual CPUs is caused. This is a problem existing in the prior art. Aiming at the problem, the main CPU of the invention in a dual-CPU system comprising the main CPU and the controlled CPU comprises an application program generating an instruction signal which controls the GPIO of the controlled CPU, an Radio Interface Layer ( RIL) driver driving the controlled CPU, an RIL proxy server calling a corresponding function of the application and the RIL driver and transmitting the instruction signal generated therefrom to the RIL agent server. The controlled CPU utilizes a instruction processor controlling the running of the GPIO of the CPU according to the instruction signal, thus overcoming the defect of insufficient of the GPIO pins in the dual-CPU system.

Description

technical field [0001] The present invention relates to the GPIO control system of the double CPU utilizing RIL, especially about connecting various devices on the GPIO of the controlled CPU constituting the dual CPU, and using the RIL driver of the main CPU to control the GPIO of the controlled CPU using the dual CPU of RIL GPIO control system. Background technique [0002] Smartphones are a new generation of high-performance portable phones that combine the functions of portable phones and PDAs (Personal Digital Assistants) in a developmental way. Its development has made it possible to drive programs based on OS (Operation System Operating System), which cannot be realized in standard mobile phones, facilitate data communication, and synchronize with PC (Personal Computer). [0003] Compared with the low-capacity memory of ordinary mobile phones, smart phones use a large-capacity memory under the OS, and can use various programs and data, and can update the OS itself or ...
