摘　　要：以输出20位二进制数据为例,设计了一个基于FPGA的数据输出显示电路。分析了N位二进制-BCD转换算法和LCD显示控制电路的设计原理与方法,并以此为根据,应用EDA技术设计了一种实现基于FPGA的数据输出显示电路。其基本原理是将二进制码表示中各个数码往左边移动一位,最高一位二进制位的数码移出二进制表示进入最低一位十进制位的8421表示中,而每个十进制位的8421表示中权为8的位的数码都移到高1位十进制位的8421表示中重新组合成新的8421表示。移位之前,要先做判断,看是否要做加三调整。Taking 20 bits binary data as an example,this paper designs a data output display circuit based on FPGA.Based on the analysis of the design principle and method of N-bit binary-BCD Conversion Algorithm and LCD display control circuit,a data output display circuit based on FPGA is designed with EDA technology.The basic principle of this design is to move each digit in the Binary Code Representation one bit to the left,and move the highest one bit out of the Binary Code Representation Into the lowest one bit 8421 representation.And each 8421 decimal bit represents the weight of the 8-bit digital moved to the high one decimal bit 8421 representation in the reorganization of the new 8421 representation.Before shifting,make a judgment to see if you want to add three adjustments.
