Research on Float Evolution Based on DSP TMS320F240
【摘要】 研究 DSP TMS3 2 0 F2 40浮点数开平方的理论方法 ,采用牛顿迭代法完成浮点数开方运算 .在DSP TMS3 2 0 F2 40上编制了一套算法 ,其结果基本符合理论要求 .该方法思路新颖、精度高、速度快 ,可移植到其它浮点数运算的单片机上
【Abstract】 Theory method of float evolution based on DSP TMS320F240 is studied. Newton iterative method is used for float evolution. An arithmetic for float evolution is programmed. It’s result accords with the theory. This method features the novel idea, high precision and rapid speed. This method may be used in other float calculation of single chip microprocessor.
