Abstract
A system on chip having two or more responder units and two or more protection units is provided. Each of the responder units comprises a set of responder elements. Each of the protection units is associated with and protects one of the responder units and is arranged to provide a group mapping. The group mapping assigns one or more group identifiers to each of the responder elements of the respective responder unit.
Claims15
A system on chip, comprising:
- two or more responder units;
- and
- two or more protection units, wherein
- each of said responder units comprises a set of responder elements,
- each of said protection units is associated with and protects one of said responder units and is arranged to
- provide a group mapping, wherein;
- said group mapping assigns one or more group identifiers to each of said responder elements of the respective responder unit and at least two of said responder elements are assigned the same group identifier by said group identifier list,
- provide a group authorization list, wherein;
- said group authorization list assigns a set of access requirements to each of said group identifiers,
- receive a request for access to one or more target responder elements among the responder elements of the respective responder unit,
- for each of said target responder elements, determine the corresponding one or more group identifiers from said group mapping and further determine the corresponding one or more sets of access requirements from said group authorization list, and
- compare said request with respect to the determined set of access requirements, to generate a request evaluation result.
