Abstract
In some embodiments, a hardware linked-list manager includes a wildcard search controller for generating corresponding queue-specific read requests from wildcard read requests. The linked-list manager may be part of an on-chip interagent switch for allowing a plurality of agents to communicate with each other. The interagent switch may include a crossbar switch and a plurality of hardware linked-list managers integrated on the chip, connected to a random access memory, and connected to the crossbar switch such that the crossbar switch is capable of connecting each of the linked-list managers to each of the agents. Each linked-list manager sends agent-generated data to the memory for storage in the memory as a linked-list element, and retrieves linked-list elements from memory in response to agent read requests. A shared free-memory linked-list manager may maintain a linked list of free memory locations, and provide free memory address locations to a linked list manager upon request.
