Abstract
An electronic device communicates according to a network protocol that defines data packets, for example EtherCAT. The device has a processor for performing input control on incoming data packets and performing output control on outgoing data packets, and a shared FIFO buffer comprising a multiuser memory. An input unit receives input data, detects the start of a respective data packet, subdivides the data packet into consecutive segments, one segment having a predetermined number of data bytes, and transfers the segment to the FIFO buffer before the next segment has been completely received. The processor accesses, in the input control, the multiuser memory for processing the segment, and, in the output control, initiates outputting the output packet before the corresponding input data packet has been completely received. An output unit transfers the segment from the FIFO buffer, and transmits the segment to the communication medium.
