摘　　要：相较于其他软硬件平台的高速优势和基于时序的特有控制方式,FPGA在通信领域中的应用愈发广泛。论文对网口、串口等多业务接口的通信数据帧加密运算的逻辑处理架构进行了分析与优化。优化后的逻辑架构实现了数据帧流式传输、快速并行处理、业务优先级仲裁,以及算法资源动态分配功能。大大减少时间开销,提高逻辑处理模块的运算效率和算力分配的灵活性。文末采用综合仿真的方法验证了该种优化的可行性。Compared with other software and hardware platforms,FPGA has high-speed advantages and unique timing-based control methods,which make it more and more widely used in the communication field.This paper analyzes and optimizes the logi-cal processing architecture of the data frame encryption operation process.The optimized logical architecture realizes data frame streaming,fast parallel processing,business priority arbitration,and dynamic allocation of algorithm resources.It reduces time overhead greatly,improves the computing efficiency of logic processing modules and the flexibility of computing power distribution.At the end of the paper,the method of comprehensive simulation is used to verify the feasibility of this kind of optimization.
