内容可寻址存储器 (CAM) 在通信系统设计领域变得越来越重要。本文研究了多种适合在 FPGA 上实现的 CAM 设计。基于寄存器、RAM 块和 LUT 检查三种基本设计。设计综合了速度和面积成本,并进行了评估。这展示了如何设计 CAM 以便在无法使用 CAM 的中小型应用中的 FPGA 中使用。
Content Addressable Memory (CAM) is becoming increasingly important in the area of communication systems design. This paper investigates a number of CAM designs suitable for implementation on FPGA. Three fundamental designs are examined based on registers, RAM blocks and LUTs. The designs are synthesized with speed and area costs presented and evaluated. This shows how CAMs can be designed for use in FPGA’s in small to medium size applications where a CAM is otherwise unavailable.
