An Embedded Flexible Content-Addressable Memory Core for Inclusion in a Field-Programmable Gate Array

This paper describes a novel architecture for a contentaddressable memory core which is intended to be included in a Field-Programmable Gate Array or an Embedded Programmable Logic Core. Compared to a standard contentaddressable memory, our architecture allows for arbitrary data and tag widths; this flexibility is vital in FPGA applications, since the size of the data and tag fields are not known when the FPGA is manufactured. 1.0 Introduction1 Recent years have seen impressive improvements in the achievable density of integrated circuits. Accompanying these improvements, however, is a dramatic increase in the cost of fabricating an integrated circuit. No matter how seamless the integrated circui
