Application scheme of natural logarithmic converter based on EP1C6Q240C8 chip and CORD IC algorithm

introduction When hardware is required to implement logarithmic operations, its accuracy and speed must be considered. At present, the methods for implementing logarithmic transformation by hardware mainly include look-up table method, Taylor formula expansion method and linear approximation method. The storage unit required by the look-up table method increases exponentially with the increase in precision […]
