Networks-On-Chip Based on Dynamic Wormhole Packet Identity Mapping Management

Abstract EN

This paper presents a network-on-chip (NoC) with flexible infrastructure based on dynamic wormhole packet identity management.

The NoCs are developed based on a VHDL approach and support the design flexibility.

The on-chip router uses a wormhole packet switching method with a synchronous parallel pipeline technique.

Routing algorithms and dynamic wormhole local packet identity (ID-tag) mapping management are proposed to support a wire sharing methodology and an ID slot division multiplexing technique.

At each communication link, flits belonging to the same message have the same local ID-tag, and the ID-tag is updated before the packet enters the next communication link by using an ID-tag mapping management unit.

Therefore, flits from different messages can be interleaved, identified, and routed according to their allocated ID slots.

Our NoC guarantees in order and lossless message delivery.
