摘要
设计了一种Android手机系统框架下的基带NV数据保存方案。主要包括方案的总体框架、AP侧数据接收和保存流程、CP侧NV数据发送流程、扩展的ⅡC通信机制的设计,以及方案验证与结果分析等。在由Cortex A9核心的四核AP芯片和ARM9核心的单核CP芯片组成的手机硬件系统上实现和测试了该方案。验证结果表明,该基带NV数据导出方案具有良好的可靠性和可行性,可以应用于实际的商业产品中。
A method solution of saving the baseband NV data in Android cellphone is designed and realized.It includes the general framework of the design,data receiving and saving workflow of the AP part,NV data sending process in CP part,and the design of the enhanced ⅡC communication mechanism.Then the method is implemented on the hardware system with Cortex A9Quad-core AP chip and ARM9 CP chip.The results of implementation show that this method has a high efficiency and good reliability to export baseband NV data.It is adequate for commercial products.
