一种3G智能手机中双CPU通信方案设计

双芯片架构的提出是手机从简单功能的Future Phone转变为功能多样的Smart Phone的重大里程碑,但是双芯片间数据通信、功耗控制是该架构面临的一个难题。设计了一种双CPU的通信方案,包括控制功能、数据传输和低功耗设计。同时给出了详细的系统实现框图,并就数据传输和低功耗要求给出了解决方案。该系统方案在实际应用中取得了良好的效果。

The dual-CPU communication design program in 3G smart phone

For the conversion from future phone to smart phone, the proposed of two-chip architecture is important milestones. However, the data communication and power control between two-chip are enormous challenges for the architecture. A dual-CPU communication program is designed in this paper, which include control, data transmission, low-power design. At the same time, detailed block diagram of system implementation and the solution for the data transmission and low-power are presented. This program has achieved good results in practical application.
