DSP数字信号处理器的浮点数正弦的实现

Research of Float Sine Based on DSP Digital Signal Processor

研究浮点数求正弦的理论方法。该方法通过采用幂级数偏置展开法完成浮点数正弦运算 ,并在DSPTMS32 0F2 40上编制了一套算法。该方法思路新颖、精度高、速度快 ,可移植到其他浮点数运算的单片机上。

This paper study theory method of float sine based on DSP TMS320F240. The power series spread for calculating float sine is used. A arithmetic is designed for DSP TMS320F240. Its precision is high and speed is rapid.
