Abstract :
Theoretical motivations for using a fast and accurate single-tone frequency estimator called the Crozier algorithm are presented. An architectural study shows that with its linear complexity, it is well suited to both hardware and software implementations. It has been implemented on one hardware (Xilinx XCV1000 FPGA) and two software (ARM940T and Pentium III) platforms and their performances are compared.
