codec engine代码阅读一---根目录下的package.xdc

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

Package.xdc -------------描述该包的名称，版本信息，依赖文件，模块信息等

不看版权声明部分，正文的第一行应该是：

/* This "requires" list describes what packages to import into this bundle */

requires ti.sdo.ce;

requires ti.sdo.ce.node;

requires ti.sdo.ce.ipc;

requires ti.sdo.ce.ipc.bios;

requires ti.sdo.ce.ipc.dsplink;

requires ti.sdo.ce.ipc.dsplink.dsp;

requires ti.sdo.ce.ipc.linux;

requires ti.sdo.ce.ipc.noOS;

复制代码
下面是好多行的requires语句。注释内部说：这个requires列表描述的是要包含到这个bundle里面的包们。

requires列表下面也没什么内容了，全部内容是：

/*!

* ======== codec_engine ========

* The Codec Engine product package. //codec engine产品包

*

* 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

* 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

* 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.

*

*/

package codec_engine_2_23_01 [1, 0, 0] {

} //这个结构的含义还不了解.

复制代码
bundle本意是包,捆.实际上这里说的就是包的集合.

然后我们看都require一些什么:

requires ti.sdo.ce; //ce-codec engine

requires ti.sdo.ce.node; //codec engine节点

requires ti.sdo.ce.ipc; //ipc=inter process communication 进程间通信的包.

requires ti.sdo.ce.ipc.bios; //进程间通信的bios部分

requires ti.sdo.ce.ipc.dsplink; //进程间通信用到的dsplink

requires ti.sdo.ce.ipc.dsplink.dsp; //进程间通信用到的dsplink中的dsp部分

requires ti.sdo.ce.ipc.linux; //进程间通信的linux部分

requires ti.sdo.ce.ipc.noOS; //无操作系统情况下的进程间通信.

requires ti.sdo.ce.osal; //这个不懂
