CCS学习教程<>本章概述CCS（Code Composer Studio)软件开发过程、CCS组件及CCS使用的文件和变量。
CCS提供了配置、建立、调试、跟踪和分析程序的工具，它便于实时、嵌入式信号处理程序的编制和测试，它能够加速开发进程，提高工作效率。
<>CCS提供了基本的代码生成工具，它们具有一系列的调试、分析能力。
CCS支持如下所示的开发周期的所有阶段。
在使用本教程之前，必须完成下述工作：o 安装目标板和驱动软件。
按照随目标板所提供的说明书安装。
如果你正在用仿真器或目标板，其驱动软件已随目标板提供，你可以按产品的安装指南逐步安装。
o 安装CCS.遵循安装说明书安装。
如果你已有CCS仿真器和TMS320c54X代码生成工具，但没有完整的CCS，你可以按第二章和第四章所述的步骤进行安装。
o 运行CCS安装程序SETUP. 你可以按步骤执行第二章和第四章的实验。
SETUP程序允许CCS使用为目标板所安装的驱动程序。
CCS包括如下各部分：o CCS代码生成工具：参见1.2节o CCS集成开发环境（IDE）：参见1.3节o DSP/BIOS插件程序和API：参见1.4节o RTDX插件、主机接口和API：参见1.5节CCS构成及接口见图1-1。
图1-1 CCS构成及接口<>代码生成工具奠定了CCS所提供的开发环境的基础。
图1-2是一个典型的软件开发流程图，图中阴影部分表示通常的C语言开发途径，其它部分是为了强化开发过程而设置的附加功能。
图1-2 软件开发流程图1-2描述的工具如下：o C编译器(C compiler) 产生汇编语言源代码，其细节参见TMS320C54x最优化C编译器用户指南。
o 汇编器(assembler)把汇编语言源文件翻译成机器语言目标文件，机器语言格式为公用目标格式（COFF），其细节参见TMS320C54x汇编语言工具用户指南。
o 连接器(linker)把多个目标文件组合成单个可执行目标模块。
