摘要

Abstract

In order to achieve the goal of the laser interference measurement signal being in high speed and high precision subdivision,the division of tangent subdivision algorithm is improved. The successive approximation algorithm instead of using shift subtraction algorithm is used more in the past. Experiments prove that successive approximation algorithm is faster than shift subtractionm,resource usage is less. successive approximation algorithm is more suitable for FPGA based on high speed and high precision requirements.
