Packetized data transmissions in a switched router architecture

摘要: A switched router for transmitting packetized data concurrently between a plurality of devices coupled to the router. The are I/O ports is then programmed route packets from various source several destination ports. Different may be transmitted through comprised command word containing information corresponding packet routing, format, size, and transaction identification. Furthermore, include identification number routing device, used by device send back responses, tag requests that require response, type value indicating particular packet. In addition, there bits within indicate coherent transaction, guarantee bandwidth, an error during transmission, or sync barrier write ordering. Other types fetch operation with increment one, decrement clear, store logical OR, AND.
