3 Closed Performance Control Loop In the following the basic idea of the Fingerprinting approach is briefly described.
This Fingerprinting is used as the sensor element of the closed control loop.
Subsection
3.2
describes the actuator to influence the performance of the other
cores and, hence, the interferences. The complete closed control loop is presented
in Subsect.
3.3
. Figure
1
shows the setup of multicore processor and safety net
system with the integrated closed control loop. Note that our proposed closed
performance control loop does not require any additional software functionality
running on the multicore.
