DSP编程中往往过分追求性能，忽略了软件的封装，从而使得数字信号处理系统很难像“搭积木”一样集成已有算法，增加了系统的研发时间。针对上述缺憾，TI公司适时地推出了DSP算法标准——XDAIS，规范了DSP算法软件的开发，并提供了类似C++语言类的封装方式的算法接口，使得算法集成变得简单统一。本书系统介绍了XDAIS基本概念、软件编程规范和接口规范，并阐述了CCS中的相关工具的使用。

该书适合DSP软件编程人员作为工作工具使用，也可作为大学DSP相关课程的参考书使用。-DSP programming is often excessive pursuit of performance, ignoring the software package, which makes digital signal processing systems is difficult as the " building blocks" , as integrated existing algorithms, increasing the system' s development time. In response to these shortcomings, TI company launched a timely manner DSP Algorithm Standard- XDAIS, standardized software development for DSP algorithms, and provides a similar C++ language class is encapsulated algorithm interface, making it easy to integrate unified algorithm. This book introduces the basic concepts XDAIS, software, programming specifications and interface specifications and elaborated in CCS related tools. The book is suitable DSP software programmers to use as a working tool, but also as a reference book for university use DSP-related courses.
