Zusammenfassung:PURPOSE: An adaptive process scheduling method for embedded Linux is provided to improve performance and to omit the unnecessary occurrence of context switching. CONSTITUTION: The occupancy time per process of at least one process is calculated(S110). If adaptive processing scheduling is necessary, a pre-determined weight to be applied to a CPU occupancy time per process is calculated(S120, S130). Unless the adaptive processing scheduling is necessary, the pre-determined weigh is set as 1(S131). The CPU occupancy time per process is updated by applying the pre-determined weight to the CPU occupancy time per process(S140).
