Abstract
Sometimes, there is little interest by algorithm developers in creating a fixed-point simulation from a floating-point algorithm. However, often it is vital that high levels of speech quality be maintained in a fixed-point application. The process of converting floating-point simulations to fixed-point is time consuming, expensive, and if not done well, a state-of-the-art algorithm may never see product implementation. There is a critical need for software tools that reduce the time and effort that algorithm developers spend on floating-point to fixed-point software conversion. Bit-Exact C++ (BEC++) is just such a tool. This paper discusses a fixed-point software implementation tool, BEC++, with syntax similar in look and feel to that of floating-point C. Based on the ETSI Bit-Exact C (BEC) software now commonly used in industry, BEC++ extends the capabilities of BEC through the introduction of C++ language features and object-oriented techniques. This paper also details how to use the software, providing comparisons between BEC++ and BEC implementations.
有时,算法开发人员对从浮点算法创建定点模拟不太感兴趣。然而,在定点应用程序中保持高水平的语音质量通常是至关重要的。将浮点模拟转换为定点模拟的过程既耗时又昂贵,如果做得不好,最先进的算法可能永远不会看到产品实现。迫切需要能够减少算法开发人员在浮点到定点软件转换上花费的时间和精力的软件工具。位精确c++ (BEC++)就是这样一个工具。本文讨论了一种与浮点C语法相似的语法实现工具——BEC++。BEC++在目前工业上普遍使用的ETSI Bit-Exact C (BEC)软件的基础上,通过引入c++语言特性和面向对象技术,扩展了BEC的功能。本文还详细介绍了该软件的使用方法,并对BEC++和BEC实现进行了比较。
