A Design That Incorporates Adaptive Reservation into Mixed-Criticality Systems

Budget reestimation calculations, -axis denotes the number of execution time samples since the first job released by ; -axis denotes the processor capacity actually consumed during each job execution.

(a) Budget reestimation calculation on fixed intervals: The red arrows indicate the earliest time for the system to react to the increase of ’s consumption when configuring the system with small (below) and big estimation intervals (above)

(b) Dynamically triggered budget reestimation calculation
