Abstract

The present invention relates to an electronic device that comprises first and second processing units (IP1, IP2) for processing data. The electronic device furthermore comprises a network based interconnect (NoC) coupled to the first and second processing units (IP1, IP2) thru a network interface (Nl1, NI2). The network interface (Nl1, NI2) is used for managing the communication of the first and second processing units (IP1, IP2). The first and second processing units (IP1, IP2) communicate via request and response channels (REQ, RESP) to write data to each other. In accordance with the present invention, the request channel (REQ1) of a communication (C1) between the first and second processing units (IP1, IP2) is shared with the response channel (RESP2) of a communication (C2) between the second and first processing units (IP2, IP1), and vice versa.
