ROHC协议是IETF专门针对无线链路的特点而设计的包头压缩规范,CRC码的产生、校验和更新是其中重要的组成部分。在分析CRC快速准确并行算法的基础上,针对ROHC中具体应用要求,给出其CRC计算的硬件并行实现设计方案,并用Verilog HDL语言编写代码进行了仿真和验证,结果表明此方案具有很好的实用性和灵活性。 The ROHC protocol is a header compression specification specifically designed by the IETF for wireless links. The generation, verification and updating of CRC codes are an important part of the ROHC protocol. Based on the analysis of CRC fast and accurate parallel algorithm, aiming at the specific application requirements of ROHC, a hardware parallel implementation scheme of CRC calculation is given. The code in Verilog HDL language is simulated and verified. The results show that this scheme has a good Practicality and flexibility.
