Study of CORDIC Algorithm Based on Fixed-DSP
-
Abstract
The solution of high precision phase is a significant procedure in distance measurement system of femtosecond laser tracker. In order to match the requirement in precision of phase in fixed-DSP, hybrid radix algorithm was proposed on the basis of traditional coordinate rotation digital computer (CORDIC) after study on traditional CORDIC Algorithm. The feasibility of hybrid radix has been demonstrated and two different methods have been implemented on TMS320VC5402 showing that hybrid algorithm, which saves execution times and hardware spaces, can realize the same precision as traditional CORDIC algorithm.
