摘　　要：提出了模糊CMAC网络的一种基于FPGA的硬件实现方法。首先,分析了模糊CMAC网络的结构与算法,并以MAT-LAB仿真为依据,得到模糊CMAC网络的FPGA实现所需的参数;在此基础上,对模糊CMAC网络进行硬件模块划分,基于VHDL实现了各硬件模块的功能描述,并对模块结构进行了优化;最后,在特定的FPGA器件上实现了模糊CMAC网络。测试结果表明:该模糊CMAC网络硬件实现具有速度快、精度高的特点,且占用较少的硬件资源,是SOPC中实现模糊CMAC网络模块的一种有效方法。This paper proposes a method of hardware implementation of fuzzy CMAC based on FPGA. First, it analyzes the structure and arithmetic of fuzzy CMAC, then obtains the parameters for FPGA implementation according to MATAB simulation. After that, it partitions hardware blocks for fuzzy CMAC and implements the function of each hardware block with VHDL. Besides, it optimizes the structure of the blocks .At last, it implements the fuzzy CMAC based on a given FPGA. The test result shows that the hardware im- plementation of the fuzzy CMAC comprises the characteristics of high speed, good precision, and less chip resource. It is an effective method in implementing the modular of fuzzy CMAC in SOPC.
