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?
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,];

Runxdc.sh样本代码:

package.bld样本代码:

+ expand sourceview plaincopy to clipboardprint?
var targs = [MVArm9, Linux86];   
var profiles = ["debug", "release"];   
//  Define the base name for the executable(s) built   
var basename = "app";   
//  The following code uses the java.io.File.list() method to generate an array

                csources.push(sources[i]);   
}   
  
//  The build phase cycles through the arrays of build targets and profiles   
//       and adds an executable for each combination   
  
for (var i = 0; i < targs.length; i++) {   
     for(var j = 0; j < profiles.length; j++){   
        Pkg.addExecutable( basename + "_" + profiles[j], targs[i],   
targs[i].platform, {   
                     cfgScript: null,   
                     profile: profiles[j],   
                }   
                ).addObjects( csources );   
     }   
}  
var targs = [MVArm9, Linux86];
var profiles = ["debug", "release"];
//  Define the base name for the executable(s) built
var basename = "app";
//  The following code uses the java.io.File.list() method to generate an array
//      of all files in the current directory ('.') and then sorts out .c files
var sources = java.io.File('.').list();
var csources = [];
for (var i = 0; i < sources.length; i++){
       if(String(sources[i]).match(/.*.c$/))
                csources.push(sources[i]);
}
//  The build phase cycles through the arrays of build targets and profiles

for (var i = 0; i < targs.length; i++) {
     for(var j = 0; j < profiles.length; j++){
        Pkg.addExecutable( basename + "_" + profiles[j], targs[i],
targs[i].platform, {
                     cfgScript: null,
                     profile: profiles[j],
                }
                ).addObjects( csources );
     }
}

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：

augroup filetypedetect   
au BufNewFile,BufRead *.bld setf javascript   
augroup END
