74LS166在CRC编码中的应用

The application of 74LS166 in CRC code

循环冗余检验(CRC:cyclic redundancy check)由于编码简单且有效.是一种最常用的信道编码方法.输入数据的并行/串行转换是串行CRC运算中的重要部分。本文以CRC-8为例.选用集成电路芯片74LS166,在Altera公司的QuartusⅡ软件下.采用原理图输入的方法进行了编译和仿真.成功地完成了数据的并行/串行转换功能。

Because of codes simple and effective, cyclic redundancy check is one most commonly used channel coding method. The data-in parallel/serial transformation is an important part in the serial CRC operation. This paper takes CRC-8 as an example, selects integrated circuit chip 74LS166, in Altera Corporation＇s Quartus II software, used the schematic diagram input the method to carry on the compiling and the simulation. It has completed the data parallel/serial transformation function successfully.
