fixed point operation meaning in English

定点操作
定点运算

Since the reference open source codes are written in float ansi c language , while the target processor just has the effort to cope with fixed point operation , a formal modeling method must be applied to developed a set of fixed point ansi c code , and transfer the dsp application developing procedure into a traditional way . the fixed point toolbox within matlab is adopted to play this role
鉴于目标处理器只有定点处理能力,而ilbc算法的参考实现源代码是浮点ansic代码集。总的实现方案采用了matlab定点工具箱作为建模的工具,通过建立了完整的算法定点模型实现浮点到定点的转换,并进一步开发出了定点ansic代码集。
