Abstract
Multi﹣channel data aligner is a common digital circuit in the high﹣speed and real﹣time signal processing systems with field programmable gate array(FPGA)architecture.This paper introduces a method of multi﹣channel data auto﹣alignment based parameterization method on VHDL language.Multi﹣channel data is cached separately and then the synchronous sign﹣flags are detected and the addresses are registered.At last,all data are read out synchronously.Separating from the multi﹣channel alignment logics and setting dif﹣ferent synchronous flags detection circuits,the method can adapt different application.It has simple structure and good scalability.It performs processing with minimal data loss to achieve continuous data stream.Also the problem of asynchronous clock is resolved.Two circuit designs using this method are introduced,and simulation and programming are made for validation.关键词
