simple code of some kind of base decoder based on verilog

线性反馈移位寄存器的最右侧位称为输出位。水龙头是 XOR 按顺序和输出位，然后反馈到最左边的位。在最右边的位置的位序列的叫做输出流。双边投资条约中的线性反馈移位寄存器状态影响输入被称为水龙头 （在图中的白色）

Content-addressable memory (CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory, associative storage, or associative array, although the last term is more often used for a programming data structure.

说明：  I2C verilog code I2C僅使用兩個雙向開漏線，串列資料線（SDA）和串列時鐘線（SCL），上拉了電阻。使用的典型電壓是+5 V或+3.3 V（雖然其他電壓系統也是允許的）。 在I2C參考設計中，使用7位或10位（取決於所使用的裝置）位址空間。普通I2C匯流排速度為100 kbit / s的標準模式和10 kbit / s的低速模式，但任意低時脈速率也是允許的。 I2C的最新修訂可以承載更多的節點，並以更快的速度執行[b]。這些速度被更廣泛地使用在嵌入式系統中而不是PC上。I2C也有其他的特性，例如16位元尋址。(I2C verilog code I2C (Inter-Integrated Circuit))

ADC Reference code!Clock 100kHz

该程序实现的是10进制的计数器，具有置位复位的功能。-the program is the band of 10 counters, with the home-reset function.

FPGA三国论战，入门介绍和高端见解！对于FPGA初学者很有用。(Three FPGA controversy, and high-end introduction to ideas! For FPGA useful for beginners.)

学习ISE的好资料，想要使用XILINX芯片进行开发必看(ISE learning good information, want to use a must-see XILINX chip development)

这是一段写pwm的硬件程序，通过不同的占空比控制不同led灯的亮度，这样可以很好地体现vhdl的硬件代码的优点，     

说明：  In the data management system a significant role of the Data link layer is to convert the unreliable physical link between reader and tag into a reliable link. Therefore, the RFID system employs the Cyclic Redundancy Check (CRC) as an error detection scheme. In addition for reader to communicate with the multiple tags, an anti-collision technique is required. The technique is to coordinate the communication between the reader and the tags. The common deterministic anti-collision techniques are based on the Tree algorithm such as the Binary Tree and the Query Tree algorithms.
