Study Notes
Routing in Network on Chip (NoC)
- Routing paths in a Network on Chip (NoC) refer to the paths taken by data packets as they travel from source to destination nodes in the network.
Control in NoC Routing
- Global control in NoC routing involves a centralized controller that makes routing decisions for the entire network.
- Local control in NoC routing involves distributed controllers at each node, making routing decisions independently.
Distinguishing Characteristics of Global and Local Control
- Global control is distinguished from local control by the level of centralization, with global control being highly centralized and local control being distributed.
Disadvantages of Global Control
- A disadvantage of the global controller approach in NoC routing is that it can become a bottleneck, limiting the scalability of the network.
Routing Decisions in Local Control
- In local control of NoC routing, routing decisions are made by each node based on local information and communication with neighboring nodes.
Advantages of Local Control
- An advantage of local control in NoC routing is that it provides greater flexibility and adaptability, allowing the network to respond to changes and faults more effectively.
