Abstract: A method for constructing off-line a sequencing plan for a plurality of tasks executed on a real-time system, including decomposing each task into a sequence of frames, where each frame is associated with an elementary process having an execution need, and defines a start date from which the process can start and an end date, or deadline, at which the process must complete; associating respective order constraints with pairs of processes; projecting the dates on a time scale associated with an execution unit of the real-time system, thus forming a sequence of time slots; sequentially parsing the time slots of the sequence; identifying eligible processes in a current time slot, a process being eligible if it meets the following two criteria: i) it is executable in the current time slot, and ii) if it has an order constraint.

Abstract: A system for executing code with blind hypervision mechanism comprises: at least one addressable physical memory, a processor operating in at least two modes, a mode termed initialization making it possible to define at least one partition in the memory and at least one second mode termed nominal, a memory bus linking the processor to the memory, a memory partitioning unit positioned on the memory bus, the unit being adapted for restricting memory access to the partition currently executing when the processor is in a mode other than the initialization mode.
