1. Network based System on Chip Students: Medvedev Alexey Shimon Ofir Supervisor: Walter Isaschar (Zigmond) Winter-Spring 2006

2. Problem In modern high-speed systems that contain a lot of components traffic is a major problem. Components are interacting with each other using a bus.

3. Problem

4. This architecture has certain disadvantages:  low speed,  allows to connect only two components at a given time,  no parallel access,  unconfigurable.

5. Solution

6. On-chip packet-switched networks have been proposed as a solution for the problem of global interconnect in deep sub-micron VLSI Systems on Chip (SoC).

7. Solution Networks on Chip (NoC) can address and contain major physical issues such as  parallelization,  noise,  error correction,  speed optimization. NoC can also improve design productivity by supporting modularity and reuse of complex cores, thus enabling a higher level of abstraction in architectural modeling of future systems.

8. Project Goals Understand NoC protocol Implement NoC and NoC router using a FPGA system Implement Flow Control Unit and Hot-Spot Controller

9. Example: FCU Hot-Spot Data High Priority Data Low Priority Data R Transmissio n Request Data

10. NoC Router Switch Buffers (with Virtual Channels and wormhole data transfer)

11. Virtual Channels & Wormholes Wormhole means that the data is transmitted in a constant flow rather than in packets. Using virtual channel we can manage to transmit more than one data stream through a router.
