Customized ADC Control Interface Based on Cyclone iv FPGAs Complements high-speed data acquisition, storage and processing with complex system timing. The collected data are segmented according to the curvature and processed by the fast wavelet denoising algorithm, and then gray relational analysis is performed with the reference cloud data. Experiments show that the design system has high integration and better consistency of measurement results.
