  1. Axel Jantsch Laboratory of Electronics and Computer Systems, Royal Institute of Technology, Stockholm Networks on ChipA Paradigm Change ? Axel Jantsch

  2. Challange: How do we organize a chip with one or several billion of transistors? Axel Jantsch

  3. Why can’t we just continue?Trends and Challenges • Deep submicron effects • Communication versus Computation • Global synchrony • Design productivity gap • Heterogeneity of functions Axel Jantsch

  4. Arbitrary Composability • Given: Set of components C and combinators O • A1, A2: assamblages of components • B is a component • (C,O) is arbitrarily compasable ifA1 + B => A2can be done with effort independent of size (A1) A1 A2 => + B Axel Jantsch

  5. Network on Chip Axel Jantsch

  6. What is a NoC based Platform? A Platform is defined by • (A) the communication infra-structure from the physical level to the application level; • (B) the provided services (e.g. load balancing, power management, fault-tolerance, resource allocation, task scheduling, external I/O, etc.); • (C) the design methodology mapping and implementing applications to the platform. Axel Jantsch

  7. How does a NoC Platform help? • Reuse • Predictability Axel Jantsch

  8. Reuse • Components and resources • Communication infra-structure • Reuse of the physical design • Lower level communication services • Higher level communication services • Network services (operating system and middleware) • Application parts and features • Design, simulation and prototype environment • Verification effort Axel Jantsch

  9. Predictability • Communication performance • Electrical properties • Design and verification time Axel Jantsch

  10. The price we pay Less optimal products Axel Jantsch

  11. Development of NOC based systems High-perforrmance communication systems High-capacity communication systems Baseband platform Personal assistant Database platform Data collection systems BACKBONE Multimedia platform Entertainment devices PLATFORMS Virtual reality games SYSTEMS Axel Jantsch

  12. A NoC Platform Based Design Process • Configuring the platform • Selecting resources • Reuse of features • Evaluation and integration Axel Jantsch

  13. Conclusion • Arbitrary composability at physical, architectural, and application level is necessary • If NoC can deliver that it will significantly change design and architecture of SoCs Axel Jantsch

  14. Status of Research at KTH • Definition of the protocol stack up to the transport layer • Design of a buffer-less switch and a hot-potato routing technique • NoC simulator • Fault model and error handling scheme • Development of a quasy-sycnhronous clocking scheme • Development of a NoC Assamble Language Axel Jantsch
