本文介绍了三种类型的多值内容寻址存储器(CAM):普通CAM、距离d CAM和 * CAM。普通的CAM要求完全匹配,而 * CAM允许完全匹配。在距离为d的CAM中,即使最多d个数字不同,也会发生匹配。然后,我们定义多值CAM功能表示这些CAM。接下来,我们展示了通过LUT级联来实现每个CAM功能的方法,LUT级联是RAM的串联连接。两个值和多值的情况下的实验结果。
In this paper, we introduce three types of multiplevalued content-addressable memories (CAMs): ordinary CAMs (CAMs), distance d CAMs, and *CAMs. Ordinary CAMs require an exact match, while *CAMs allow wildcard matches. In a distance d CAM, a match occurs even if at most d digits differ. Then, we define multiple-valued CAM functions represented by these CAMs. Next, we show an approach to realize each CAM function by an LUT cascade, which is a series connection of RAMs. Experimental results for both two-valued and multi-valued cases are shown.
