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,它包括一系列工具，这些工具可以允许你将你的C语言代码组织成类似于java的包管理方式，具有面向对象的特性，因为它还有一个名字，叫做eXpanDed
C.
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?
-
var MVArm9 = xdc.useModule("gnu.targets.MVArm9");
-
MVArm9.rootDir = "/opt/DVS357/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le";
-
MVArm9.lnkOpts.suffix = "-lpthread " + MVArm9.lnkOpts.suffix;
-
var Linux86=xdc.useModule("gnu.targets.Linux86");
-
Linux86.rootDir = "/usr";
-
Linux86.lnkOpts.suffix = "-lpthread " + Linux86.lnkOpts.suffix;
-
Build.targets = [ Linux86,MVArm9,];
-
var MVArm9 = xdc.useModule("gnu.targets.MVArm9");
-
MVArm9.rootDir = "/opt/DVS357/mv_pro_4.0/montavista/pro/devkit/arm/v5t_le";
-
MVArm9.lnkOpts.suffix = "-lpthread " + MVArm9.lnkOpts.suffix;
-
var Linux86=xdc.useModule("gnu.targets.Linux86");
-
Linux86.rootDir = "/usr";
-
Linux86.lnkOpts.suffix = "-lpthread " + Linux86.lnkOpts.suffix;
-
Build.targets = [ Linux86,MVArm9,];
