[Abstract]:With the popularization of Android open source mobile operating system based on Linux kernel and the development of application processor, the research and application of smart phone has been developed rapidly. NIVIDA AP20H processor adopts dual-core Cortex A9 architecture. Integrating GPU, audio and video processors and other functional modules through SoC technology, it is a powerful application processor for smart phone design. TD-SCDMA is the third generation mobile communication standard. It is the third generation mobile communication standard which is put forward by our country for the first time and mainly based on intellectual property rights of our country. It has important strategic significance in the history of telecommunication development in our country. In this paper, the design of the key circuit of TD-SCDMA smart phone based on NIVIDA dual-core application processor is studied, which is based on the case of China Mobile custom-made mobile phone. The main contents are as follows:. 1. The ARM dual core application processor and the key circuit design techniques used in the design of smart phone based on dual core processor are introduced. 2. The hardware design of the key modules in the hardware design of TD-SCDMA smart phone based on AP20H dual-core application processor is described in detail, and the power supply design of the whole system is analyzed in detail, and the power consumption design of the whole system is optimized. The interconnect interface design flow, key measures and optimization points of application processor and baseband processor are systematically studied and discussed in order to improve the stability of the system. Ensure that all functional requirements can be met, and fully consider power saving performance. 3. The technical analysis of the problems encountered in the circuit design is carried out in detail, and the complete treatment scheme and solving measures are put forward, and a typical case analysis is given. In this paper, the hardware design of smart phone with dual-core application processor and baseband processor can be quickly mastered by the mobile phone circuit design engineer. It lays a solid foundation for the rapid design of high-end TD-SCDMA mobile phones that meet the needs of operators.
