Design and Performance Evaluation of Network Architectures for Systems
on Chip / Parallel
and Distributed Systems
Research Activities
- Model engineering
- model development
- complexity reduction
- automatic model generation
- Modeling techniques for performance evaluation
- Markov chains (discrete-time, continuous-time)
- Petri nets (stochastic, timed, colored)
- Simulation (steady-state, terminating, MRIP)
- Applications of main interest:
- embedded systems / system on chip: design, architecture
- network on chip: topologies, performance
- real-time systems: mobile communication, embedded
- wired/wireless network architectures:
topology, buffer size, switch size, etc.
- network traffic: distribution in time (multifractal traffic, bursts,
arrival times) and space (multicast, hot spot)
- hardware reconfiguration / self-organization:
dynamic adaption to changing environment
- Development of new network architectures for
- systems on chip / multicore processors
- parallel and distributed computer architectures
- network switches
- real-time systems
- Tool support
