codec engine代码阅读一---根目录下的package.xdc文件

[转载] http://blog.csdn.net/chenbang110/article/details/8769873

      codec engine代码是适用于XDC tools而写的，因此看代码之前要对XDC tools有一些基本的了解，可以参考:TI XDC工具入门简介

http://blog.csdn.net/u010186001/article/details/52863787

      Package.xdc可用于描述该包的名称，版本信息，依赖文件，模块信息等。

     根目录下的package.xdc，不看版权声明部分，正文的前几行是：

1. /* This "requires" list describes what packages to import into this bundle */
   
2. requires ti.sdo.ce;
   
3. requires ti.sdo.ce.node;
   
4. requires ti.sdo.ce.ipc;
   
5. requires ti.sdo.ce.ipc.bios;
   
6. requires ti.sdo.ce.ipc.dsplink;
   
7. requires ti.sdo.ce.ipc.dsplink.dsp;
   
8. requires ti.sdo.ce.ipc.linux;
   
9. requires ti.sdo.ce.ipc.noOS;

复制代码第1行注释说：这个requires列表描述的是要包含到这个bundle里面的包们。bundle本意是包,捆.实际上这里说的就是包的集合. 所有的requires语句之后的内容是：

1. /*!
   
2. *  ======== codec_engine ========
   
3. *  The Codec Engine product package.  //codec engine产品包
   
4. *
   
5. *  This package is a "bundle" of packages required to use the Codec Engine//这个包是一个要使用codec engine api来运行
   
6. *  API's to run algorithms.  It also includes packages required to add new  //算法所需要的包的bundle.这也包含了一些
   
7. *  algorithms to a system using the Codec Engine.                                     //加使用codec engine的系统增加新算法所需的包.
   
8. *
   
9. */
   
10. package codec_engine_2_23_01 [1, 0, 0] {
    
11. }                //这个结构的含义还不了解.
    

复制代码
附上所有的require语句（上述只是一小部分）:

1. requires ti.sdo.ce;   //ce-codec engine
   
2. requires ti.sdo.ce.node; //codec engine节点
   
3. requires ti.sdo.ce.ipc;    //ipc=inter process communication 进程间通信的包.
   
4. requires ti.sdo.ce.ipc.bios;  //进程间通信的bios部分
   
5. requires ti.sdo.ce.ipc.dsplink;  //进程间通信用到的dsplink
   
6. requires ti.sdo.ce.ipc.dsplink.dsp; //进程间通信用到的dsplink中的dsp部分
   
7. requires ti.sdo.ce.ipc.linux;   //进程间通信的linux部分
   
8. requires ti.sdo.ce.ipc.noOS;  //无操作系统情况下的进程间通信.
