“…The key disadvantage is a long downtime. Therefore, an advanced communication reconfiguration using protection switching in NoCs to support reliable task migration is proposed [16,22,23], which is inspired by protection switching mechanisms from wide area transport networks. Two alternatives to migrate communication relations of a relocated task are dualcast and forwarding as shown in Fig.…”

This chapter covers the interdependencies of temperature and the reliable operation of multiprocessor systems on chip (MPSoC). Starting with the assessment of temperature values for the different cores either through measurement or estimation, it is shown which methods on system level can be applied to balance the thermal stress in the system and thus to come to an evenly distributed probability of errors. Special focus is given to task migration as a system-level means, which is supported by an on-chip interconnect virtualization technique that eases fast and transparent switch-over of communication channels. Overall, it is shown how mechanisms on different levels of the system stack can be combined to cooperate across layers for improving system reliability.

Achieving system-level dependability is a demanding task. The manifold requirements and dependability threats can no longer be statically addressed at individual abstraction layers. Instead, all components of future multi-processor systems-on-chip (MPSoCs) have to contribute to this common goal in an adaptive manner. In this paper we target a generic heterogeneous MPSoC that combines general purpose processors along with dedicated application-specific hard-wired accelerators, finegrained reconfigurable processors, and coarse-grained reconfigurable architectures. We present different reactive and proactive measures at the layers of the runtime system (online resource management), system architecture (global communication), micro architecture (individual tiles), and gate netlist (tile-internal circuits) to address dependability threats.
