| 摘要: |
| 内容可寻址存储器(CAM)是一种快速匹配存储器件，在通信、雷达等许多领域有着广泛的应用。在介绍CAM基本原理的基础上，提出了在两类新型FPGA上实现CAM的设计方法，并讨论了两种基于CAM的新型关联比较器(CP)实现途径，通过半实物仿真实验，验证了CAM和CP的实时信号处理性能。 |

| Abstract: |
| The content addressable memory (CAM) is a fast matching memory. It's widely used in communication and radars. In this article, new methods of CAM designing based on two series of FPGA are brought forward. Two approaches of coherent processor (CP) based on CAM are discussed. The real-time processing performance is supported by FPGA platform emulation. |
