VGA采用Spartan 3E板系统的VHDL

算法状态机方法是一种设计有限状态机的方法。它用来表示数字集成电路的图表。ASM图类似于状态图，但形式化程度较低，因此更易于理解。ASM图表是描述数字系统顺序操作的一种方法系统。这个这项工作的目的是通过一个用vhdl编写的算法状态机（ASM）来计算一个数的平方根的整数部分。这项工作附在用葡萄牙语编写的报告之后。

DS18B20温度传感器，用verilog语言实现(DS18B20 temperature sensor, with the verilog language)

A 4 bit twisted ring counter is a sequential circuit which produces the following sequence of output values: 0000, 1000, 1100, 1110, 1111, 0111, 0011, 0001 and then repeats. Design a circuit for a 4 bit twisted ring counter that uses four D flip flops. Draw a state transition diagram, a state table and a schematic for your circuit. Design an alternate implementation using just three flip flops and draw a state transition diagram, state table and a schematic for your circuit. If your designs are extended to implement an n bit twisted ring counter, how many flip flops are required using each of the two approaches. In what situations would you prefer the first method? In what situations would you prefer the second?
