摘要
对TMS320C3X中浮点数除法的实现方法进行了详细讨论,并给出汇编子程序。浮点数除法首先利用牛顿迭代法求出除数的倒数,然后再与被除数相乘,从而得出结果。该设计思想已经应用到实际系统中,实践证明,实现方法正确,运算效率高,具有一定的实用价值。
The method of float-point division on TMS320C3X is discussed and the assembly subroutine is provided. Float-point division is achieved by multiplying dividend by the inverse of divisor which is computed with Newton iterative algorithm. The experimental results show that the method proposed in this paper are effective and practical.
