在数字信号处理中,高速高精度的三角函数发生器有着广泛的应用。传统的方法是采用查表、多项式展开或近似的方法。这些方法在速度、精度、简单性和高效实现方面不能兼顾。对比而言,用CORDIC 实现的三角函数发生器能很好地兼顾这些方面,并且极适合于VLSI 实现。提出了一种基于流水线CORDIC的离散三角函数发生器。-In the digital signal processing, high-speed high-precision trigonometric function generator has a wide range of applications. The traditional method is the use of look-up table, polynomial or similar methods. These methods in terms of speed, precision, simplicity and efficient implementation can not take into account. In contrast, the use of CORDIC trigonometric function generator can achieve a good balance between these areas, and very suitable for VLSI realization.
