Abstract: Disclosed herein is an apparatus for continuous profiling for a multicore embedded system, the apparatus including a profiling data reception unit for receiving one or more pieces of profiling source data, in which events for each core in a multicore embedded system are written, from the multicore embedded system; a profiling data analysis unit for analyzing the profiling source data, determining a time at which each of events included in the profiling source data occurred and a core corresponding to the event, and determining whether each of the events is a past event depending on the time at which the event occurred; and a profiling file management unit for distinguishing each of the events depending on the determination of whether the event is a past event and storing the events in profiling files.

Abstract: Disclosed herein are a dynamic scheduling method for guaranteeing Quality of Service QoS depending on network transmission traffic and a system using the same. The dynamic scheduling method includes assigning communication channels to respective nodes based on Identifications (IDs) of parent nodes corresponding to the respective nodes, setting priorities for assignment of time slots to the respective nodes in each quarter based on data traffic volumes corresponding to the respective nodes, and assigning time slots to the respective nodes in each quarter depending on the set priorities for assignment of the time slots.
