Abstract

This article describes a small change to a network processor that enables the use of externally connected co-processors via the "Co-Processor Response Bus". A coprocessor manager is built into the network processor to manage this bus, allowing a co-processor to be added to the system external to the network processor. This external co-processor can be accessed by all threads within the network processor by using the co-processor manager.
