摘要
根据雷达光栅显示器的应用要求,提出一种基于FPGA的数字式正余弦函数产生器的解决方案。论述了如何用数字电路来实现正余弦函数计算的过程。方案不但可以用于雷达光栅扫描显示器的坐标变换器,而且适用于通讯领域等其它需要正余弦函数的波形产生器的场合。
According to requirement of radar display, this paper present a solution of digital SINCOS function generator based on FPGA, and discuss the process of function calculateing that used digital circuit. This solution not only suitable for use of coordinat converter of radar raster display, and suitable for others like communication field that need sin-cos waveform also.
