摘　　要：本文主要研究了DSP/BIOS实时嵌入式操作系统,深入探讨该系统的运行原理和特点,对其提供的关键系统内核对象进行详细的分析,并对系统中对象的配置和使用做了介绍。根据TD-LTE协议栈的系统构架和各子层的交互特点,结合工程实践,论述了基于DSP/BIOS系统下实现协议栈功能的方法,包括各子层的架构,层间通信,接口设计,同步机制等。尤其对实现过程中,各内核对象具体的参数配置进行了详细的分析,以便保证ID-LTE协议栈在该系统正常运行,对于更好的提高整个TD-LTE系统效率具有重要意义。This thesis mainly focuses on DSP/BIOS real-time operation system which provides real-time library and tools to develop embedded software. In this paper, it researches the basic functions, and discusses various aspects of DSP/BIOS in depth, especially that how to configure the objects. Then, it introduces the structure and characteristics of protocol stack in TD-LTE. With the specific reqtiirements, it designs and implements the protocol stack based on DSP/BIOS including method and interfaces for communication between sublayers, architecture, and synchronization. To ensure the steady run of this system, the details for configuration are discussed, which is important to erthance the efficiency of protocol stack.
