Communication processor for a packet-switched network

摘要: A packet switch receives data and processes it for assembly into packages. bus allows communication between each of the processing units one or more storage storing packets. Arbitration deciding which will be granted access to is performed by a system selectively alterably designates any at least two different levels priority units, relative percentages time priorty levels. The assures greater those having higher level priority. If provided buses, requests are alternated them. arbitration provides selective in plurality cycles including read cycle, write cycle read/modify/write grants request from unit within cycle.
