TI XDC工具入门简介

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:

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,];
