verilog编写的计算百分比模块-Verilog prepared by calculating the percentage module

---实现的部分VHDL 程序如下。 　　--- elsif clk1x event and clk1x = 1 then ---if std_logic_vector(length_no) >= “0001” and std_logic_vector(length_no) <= “1001” then -----数据帧数据由接收串行数据端移位入接收移位寄存器---rsr(0) <= rxda --- rsr(7 downto 1) <= rsr(6 downto 0) --- parity <= parity xor rsr(7) --- elsif std_logic_vector(length_no) = “1010” then --- rbr <= rsr --接收移位寄存器数据进入接收缓冲器--- ...... --- end if(--- achieve some VHDL procedure is as follows.--- Elsif clk1x event and then a clk1x = s--- if td_logic_vector (length_no))

包括VHDL、verilog在内的各种设计实例，是学习硬件描述语言的帮手。共有82个实验例子，涉及各种语法规则。-82 VHDL, verilog test case, involving a variety of grammatical rules. which is you learn the HDL language helper.

本文件时VHDL的各种编写规范，有助于开发者在平时养成好的编码习惯(This document, the various write VHDL specification, helps developers to develop good coding habits in peacetime)

说明：  ds1302时钟驱动程序，已在quartus上验证可以是直接使用(DS1302 clock driver, which has been verified on quartus, can be used directly)
