Patent ID: 8301885

Claim:
A method comprising: transferring messages via a time-controlled communication system between a plurality of IP cores including at least one privileged IP core and at least one unprivileged IP core, with each IP core having an information-processing subsystem and a network controller, with each network controller having at least two interfaces, an interface for the communication system and a second interface for the information-processing subsystem; transmitting a privileged message including transmission parameters from the at least one privileged IP core to the at least one unprivileged IP core, the transmission parameters including a periodically recurring transmission time of a time-controlled message and a maximum transmission duration after each transmission time, that are set exclusively by the at least one privileged IP core to control a network controller of the at least one unprivileged core; autonomously transmitting from each network controller a message exactly at the periodically recurring transmission time; and interrupting the transmission process at a time no later than after the assigned maximum transmission duration has elapsed.
