Expanded addressing for traffic queues and prioritization

摘要

A system of expanding addressing in an addressing constrained environment. A bus that defines a limited number of addresses couples together a master and a plurality of slaves. When each slave has multiple possible target ports, a maximum granularity provided by the addressing may be exceeded. By using a portion of a transmission header as an internal address, the maximum addressing may be expanded to greater granularity. The internal address is then translated in the slave to recover the external address in the header.
