Direct digital frequency synthesis using a modified CORDIC
Eugene Grayver, Babak Daneshrad · 1998
This paper introduces a new approach to direct digital frequency synthesis (DDFS) based on the Coordinate Rotation (CORDIC) algorithm. The modifications to the standard CORDIC algorithm introduced in this paper allow fine frequency resolution, and exhibit significant potential for low power applications. The new architecture does not need a large ROM and can be implemented on a general purpose processor, or on a flexible ASIC architecture.
