Abstract

A data processing device is described including one or more processors implementing a plurality of data processing entities, one or more software interrupt nodes and an access register for each software interrupt node. The access register specifies which one or more data processing entities of the plurality of data processing entities is/are each allowed to, as interrupt source data processing entity, trigger an interrupt service request on the software interrupt node for another one of the plurality of data processing entities as an interrupt target processing entity. Each software interrupt node is configured to forward an interrupt service request triggered by an interrupt source data processing entity which is allowed to trigger an interrupt service request on the software interrupt node to an interrupt target processing entity.
