摘要:

分析了基于ISO/IEC 18000-6协议的超高频(UHF)RFID系统数据传输中循环冗余校验(CRC)算法的原理和特点,在经典LFSR电路的基础上,采用按字节并行计算CRC校验码的方法,以CRC-CCITT生成多项式为例,用Verilog HDL语言设计实现了8位并行CRC-16电路.在Quanus Ⅱ8.0综合开发环境下进行时序仿真,并在FPGA芯片EP1C6Q24017上测试验证,结果表明:所设计的电路在一个时钟周期内处理8位数据,符合协议规定,满足超高频RFID系统的通信速率要求.

Abstract:

The principle and characteristics of cyclic redundancy check (CRC) algorithm in data transmission of ultra-high frequency (UHF) RFID system based on ISO/IEC 18000-6 protocol are analyzed, and on the basis of the classical LFSR circuit, the method of parallel calculation of CRC check code by byte is adopted, and the 8-bit parallel CRC-16 circuit is designed and implemented by Verilog HDL language by taking the CRC-CCITT generation polynomial as an example. In the Quanus II.8.0 comprehensive development environment, the timing simulation is carried out, and the test and verification are carried out on the FPGA chip EP1C6Q24017, and the results show that the designed circuit processes 8-bit data in one clock cycle, which meets the protocol requirements and meets the communication rate requirements of UHF RFID system.
