使用環境:NC-Verilog 5.4 + Debussy 5.4 v9 + Quartus II 7.2 很 多介面都採用serial傳輸,如I2C、LVDS、mini-LVDS…等,在寫入時必須將parallel資料轉成serial,讀出時又得將 serial轉成parallel,所以是個常用的電路,其原理就是使用shift register來達成,本文將一一討論parallel轉serial,serial轉parallel,也順便討論pa...
在转为十六进制,得到CRC-8的多项式简写0x07INIT:开始进行CRC校验之前寄存器的初始化预置值,以十六进制表示,在不指定的情况下默认为0x00REFIN:待进行CRC校验的数据是否进行高低位反转标志位,True或者FalseREFOUT:输出的CRC校验结果(与XOROUT异或之后的结果)是否进行高低位反转标志位,True或者FalseXOROUT:CRC校验计算结果...
