Abstract

In a cyclic executive, a series of frames are executed in sequence; once the series is complete the sequence is repeated. Within each
frame, units of computation are executed, again in sequence. In implementing cyclic executives upon multi-core platforms, there is advantage
in coordinating the execution of the cores so that frames are released at
the same time across all cores. For mixed criticality systems, the requirement for separation would additionally require that, at any time, code of
the same criticality should be executing on all cores. In this paper we derive algorithms for constructing such multiprocessor cyclic executives for
systems of periodic tasks, when inter-processor migration is permitted.
