Abstract
Provided is a circuit for signalling the real-time end of a local area network packet as the packet is being pulled off a transmission medium and stored in memory. Storage of the packet is performed by a local area network coprocessor. The circuit monitors for the simultaneous occurrence of three conditions: the coprocessor is in a write-to-memory cycle; it is writing to the address of a status word pertaining to a packet; and the most significant bit of the status word is being set. If all three conditions are true, the circuit asserts the real-time end-of-packet signal.
