Understanding parameterizable content-addressable memory

Keywords:content-addressable memory  memory cores  parameterizable  FPGA 

A content-addressable memory (CAM) does content matching rather than the address matching performed by standard memory cores. The content matching approach enables faster data searches than can be achieved by sequentially checking each address location in a standard memory for a particular value. The higher speed searches are achieved by using content values as an index into a database of address values. The additional ability to perform content compares in parallel enables even higher speed searches. A set of scripts is included with the CAM reference design that allow the customisation of width, depth, memory type, and optional features.

This document from Xilinx Inc. describes a parameterizable CAM further, and is accompanied by a reference design that replaces the CAM core previously delivered through the CORE Generator software. The CAM reference design should be used for all new FPGA designs targeting Virtex-6, Virtex-5, Virtex-4, Spartan-6, Spartan-3, Spartan-3E, Spartan-3A, Spartan-3A DSP FPGAs, and newer architectures.
