1.XDC(Express DSP Component)是TI提供的一个命令行工具,它可以生成并使用实时软件组件包。       2.以上两图说明了XDC的工作方式：通过相关文件设定操作指令，读入源码、库文件以及已经存在的组件包最终生成可执行文件。 3.Package------XDC工作的基本单元。包括有：源码、库文件以及元数据；元数据这包含有该包的版本信息和依赖信息，以及模块（Module）信息。 4.XDC使用方法：     5.XDC需要的文件：config.bld  package.bld  package.xdc Package.xdc -------------描述该包的名称，版本信息，依赖文件，模块信息等   Config.bld --------------描述XDC要使用的编译工具的相关信息，如不同CPU所使用的编译工具目录，每种编译工具的编译选项，连接选项等基本信息；  
Package.bld -------------------描述对于该包需要生成的平台，profile（debug，release）。通过Javascript脚本添加源码到生成执行文件的信息中。 Package.mak-------------------由XDC生成的文件，用于最终编译可执行文件。 6.XDC工作流程：   7.使用XDC所需的文件：源码、package.bld、package.xdc、config.bld。同时需要通过shell脚本将DVEVM的安装位置导出为环境变量。 各代码如下： Config.bld样本代码: + expand sourceview plaincopy to clipboardprint?

PS: 在 VIM中，给新的文件类型添加已知文件类型的语法高亮的方法是------在“/usr/share/vim/vimfiles/after”路径中添加一个文件“filetype.vim”（FC10系统下）,在其中添加如下代码： view plaincopy to clipboardprint?
01.augroup filetypedetect  
02.au BufNewFile,BufRead *.bld setf javascript  
03.augroup END
