As a result of critical industrial conditions of Electrostatic Precipitator( ESP),ESP controller requires a network communication module which can meet a higher level requirement. An excellent signal processing ability,as long as real-time and open communication features,are necessary for ESP controller. This paper presents a network module based on AM1808. This module takes CY7C024AV2,a dual port memory,as the way to make Inter-processor Communication( IPC) possible,so that large amount of data can be exch...
