摘要
作为通用的处理器,FPGA优势不言而喻,但也存在一些明显的不足,复数的求模取对数运算就是其中之一。介绍了一种利用CORDIC算法完成高精度的求模运算,再利用自适应查找表法实现高精度取对数运算。该流程实现简单,运行速率快。
It goes without saying that the FPGA, as the general processor, has a variety of advanta- ges. However, it also has some deficiencies such as mod operation and logarithm algorithm of the complex number. A high-precision mod operation is introduced based on the CORDIC algorithm, and then the high-precision logarithmic algorithm is realized through the adaptive lookup table （LUT） method, both of which can be easily implemented with fast operating speed.
