Noc architecture performs better comparing to bus based when the number of processors is small. On the other hand bus based performs better than noc when number of the processors is large. This leads to new architecture which is hybrid bus based architecture where each node is packet switched in a mesh network of noc architecture that contains bus based system with small number of processors. Few results showed that this hybrid architecture performs optimally better than either purely noc based or purely bus based architecture. Hybrid architecture contains a processor connected to the bus, the bus in turn connected to the router. Each processor contains a private Level 1 (L1) cache. When hybrid architecture is preferable, the optimal number of processors on each bus subsystem varies based on the application. Hence the proposed architecture allows scalable bus-based multiprocessor subsystems on each node in the NoC. This system provides a multi-bus execution environment where each processor is connected to a bus and the bus-based subsystems communicate via routers connected in a mesh-style configuration. The system can be reconfigured to vary the number of bus subsystems and the number of processors on each subsystem. This architecture provides reliability and adaptability and reduces the network delays. Implementing and presenting the details of architecture and experimental results using ns2 indicating the advantages of this architecture.
Key words: Hybrid architecture, internet protocol, multi-core, network-on-chip, reconfigurable architecture, topology,
