Mapping Publications

Task mapping plays a crucial role in the performance of the MPSoC. Several mapping heuristics were developed since 2010, aiming to: (i) optimize the communication energy; (ii) improve reliability; (iii) distribute the workload targeting the system lifetime.

Hierarchical Energy Aware Mapping (HEAT) : mapping heuristic that distributes the workload evenly into the system - uses runtime energy monitoring to guide the mapping heuristic

• Hierarchical Energy Monitoring for Task Mapping in Many-core Systems

Quality of service Publications

Runtime adaptation - This work investigates the runtime adaptation of the NoC resources (switching mode and priorities), according to the QoS requirements of each application running in the MPSoC. Deadlines, throughput and latency are monitored at runtime, and the system acts over the communication infrastructure, adapting it to reach the constraints.

  RUARO, R.; CARARA, Everton Alceu; MORAES, Fernando Gehm
  IEEE Transactions on Very Large Scale Integration Systems, 2015

QoS API - This work links the hardware level of NoCs to the MPSoC application level, proposing the development of a communication API that exposes the communication services offered by the NoC to the application developer.

• Differentiated Communication Services for NoC-Based MPSoCs
  CARARA, Everton Alceu; CALAZANS, Ney; MORAES, Fernando Gehm
