“…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.…”

“…Figure 21 shows the latencies of the depicted execution chain during the migration, which starts at 2.5 • 10 6 cycles assuming FORK is stateless. The results have been measured using an RTL implementation of the MPSoC [16]. In Fig.…”

“…The dualcast and forwarding variants enable a nearly unnoticeable migration of the tasks. However, the investigations in [16] show that when migrating tasks with state, the handling of the task migration itself becomes the dominant factor in the migration delays and outweighs the benefits of the advanced switching techniques.…”

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.
