同步串行数据发送电路SSDT的基本功能是将并行数据转换成串行数据并进行同步发送。系统写入和读出时序完全兼容Intel8086时序。 系统以同步信号开始连续发...

7段数码显示译码器设计7段数码是纯组合电路，通常的小规模专用IC，如74或4000系列的器件只能作十进制BCD码译码，然而数字系统中的数据处理和运算都是二进制的，所以输出表达都是十六进制的，为了满足十六进制数的译码显示，最方便的方法就是利用译码程序在FPGA/CPLD中来实现。例子作为七段译码器，输出信号LED7S的7位分别接数码管的7个段，高位在左，低位在右。例如当LED7S输出为“1101101”时，数码管的7个段g、f、e、d、c、b、a分别接1、1、0、1、1、0、1；接有高电平的段发亮，于是数码管显示“5”。-7 digital display decoder design 7 Digital is pure combinational circuits, usually of small-scale dedicated IC, such as 74 or 4000 Series devices can only be used to decimal BCD decoder, but digital systems in the data processing and computing are binary, so the output expression are hexadecimal, and hexadecimal number in order to meet the needs of the decoding shows that the most convenient way is to use decoding process in FPGA/CPLD in to achieve. Seven-Segment decoder as an example, the output signal of the seven were LED7S access digital pipe 7 above, high in the left, low in the right. For example, when LED7S output as
