State of the art direct digital frequency synthesis methodologies and their performance on FPGA

The Direct Digital Frequency Synthesizer (DDFS) is a critical component routinely implemented in many electronic systems. Advanced DDFS design techniques have been proposed but they optimize the performance for a given ASIC (Application Specific Integrated Circuits) technology. Nowadays, FPGA are very often used for the release of electronic systems. As a consequence, the study of the performance of advanced DDFS design techniques when implemented on FPGA devices, is of great interest. The paper presents various implementation of state of the art DDFS on various FPGA and compares their performance providing hints on optimal design as a function of the chosen performance parameter
