An ATM application specific integrated processor

Abstract

An application specific integrated processor designed for ATM cell processing applications is described in this paper. A new dedicated architecture consisting of a custom-made CPU core, a pipeline input cell buffer and a content addressable memory (CAM) is employed to realize both high performance data processing and functional re-configurability. The chip has been implemented on 0.5 /spl mu/m CMOS. It consumes 2400 mW power under 3.3 V supply at 52 MHz clock frequency for a 155 Mbps high speed cell data stream. Programs for several different applications have been developed and are running on this chip. As a result of evaluation, each application program satisfies a required performance.
