COMMUNICATION FRAME STRUCTURE FOR ETHERNET SWITCH AND REAL TIME MULTIPROCESSOR COMMUNICATION METHOD USING THEREOF

摘要

PURPOSE: A communication frame structure for an Ethernet switch and a real time multiprocessor communication method using the same are provided to efficiently arrange a time interval and use a spare time interval, thereby using a minimum frame interval. CONSTITUTION: SI(Synchronization Interval)s form FI(Frame Interval)s which equally divide the entire communication time. One frame interval transceives a packet for synchronization. RTI(Real Time Interval)s are designated as communication time slots for real time transceiving.
