Abstract

An integrated circuit (IC) comprises a network and a plurality of modules (M1, M2, M3) which communicate to each other via the network. A first module (M1) sends a plurality of requests (REQ) to at least two second modules (M2, M3, Mn) and the second modules send individual responses (RESP2, RESP3, RESPn) to the first module, indicating a result of the execution of the requests. The integrated circuit (IC) comprises a network capable of sending a single response (SRESP) to the first module (M1) dependent on the individual responses (RESP2, RESP3 up to and including RESPn) from the second modules (M2, M3, Mn). The single response (SRESP) can indicate that at least one second module has executed the requests (REQ) or that a specific error has occurred in at least one of the second modules (M2, M3, Mn). The single response (SRESP) can also indicate which types of error have occurred in the second modules (M2, M3, Mn). If various errors have occurred, the single response (SRESP) can indicate which error is the most serious error or information about all errors.
