摘　　要：选取基于ARM+DSP双核系统的C6A8168为硬件平台,根据TD-LTE系统中的设计要求,介绍了基于ARM+DSP的嵌入式双核系统从系统上电到双核完全启动的BootLoader设计和实现,包括从中断向量表的建立、主处理器启动到进入应用程序的整个过程,并重点阐述了基于ARM+DSP双核非对称架构与传统的单核处理器的BootLoader的异同。经验证,本BootLoader在实现ARM+DSP双核系统启动的同时满足了TD-LTE射频一致性系统的要求。This article selects the embedded system of C6A8168 based on ARM＋DSP, describing the design and realization of BootLoader which is to start of the system of dual-core according to the requirements of TD-LTE. It includes the path from the designing of interrupt vector and the startup of main core to the entering into the main process. And more, this article mainly de- scribes the differences between system of dual-core and that of single CPU in detail. The BootLoader starts the system of ARM＋DSP successfully as well as realizes the base requirement of the system of TD-LTE radio coherence.
