| 摘要 |
The invention relates to a method for transmitting messages via a time-controlled communication system (ZK) between a number of IP cores, with each IP core having an information-processing subsystem (IVS) and a network controller (NK) with each NK having at least two interfaces, an interface to the ZK and a second interface to the IVS, characterized in that a distinction is drawn between privileged and non-privileged messages in the ZK, and where the transmission parameters relating to the ZK of a port of an NK, such as the periodically recurring transmission time of a time-controlled message and the maximum transmission duration after each transmission time, can be set exclusively by a privileged message via the ZK or directly by a privileged entity (privileged IP core), and where each NK which intends to send a message starts to transmit the message autonomously exactly at the time of the next transmission time, and ends the transmission process at the latest after the assigned maximum transmission duration has elapsed. The invention also relates to a system-on-chip (SoC) for carrying out a method such as this. |
