METHOD AND CIRCUIT ARRANGEMENT FOR ACCESSING SLAVE UNITS IN A SYSTEM ON CHIP IN A CONTROLLED MANNER |
摘要 |
<p>A circuit arrangement and method for accessing slave units in a system on chip in a controlled manner, wherein an access of a master unit of the system on chip to one of the slave units is performed via a network-on-chip bus system using an access address, where a memory protection unit is integrated between the at least one master unit and the network-on-chip bus system, and access authorization of the master unit to a slave unit is checked by the memory protection unit by comparing the access address with specified address sections, and when an unauthorized access of the master unit to a slave unit is identified, the access address is modified by the memory protection unit such that the unauthorized access is terminated in the network-on-chip bus system.</p> |
