Abstract: In an example, an integrated circuit (IC) includes a receive circuit, a transmit circuit, and a control circuit. The receive circuit includes a receive data path and a receive control interface, the receive data path coupled to store received transmission control protocol (TCP) data for a plurality of TCP sessions in a respective plurality of receive buffers in an external memory circuit external to the IC. The transmit circuit includes a transmit data path and a transmit control interface, the transmit data path coupled to read TCP data to be transmitted for the plurality of TCP sessions from a respective plurality of transmit buffers in the external memory circuit. The control circuit is coupled to the receive control interface and the transmit control interface, the control circuit configured to maintain data structures to maintain TCP state information for the plurality of TCP sessions.
