Abstract: In an embodiment a system on chip includes a plurality of microprocessors, a plurality of slave resources, an interconnection circuit coupled between the microprocessors and the slave resources, the interconnection circuit configured to route transactions between the microprocessors and the slave resources and a processing controller configured to allow a user of the system to implement within the system at least one configuration diagram of the system defined by a set of configuration pieces of information used to define an assignment of at least one microprocessor to at least some of the slave resources, select the at least one microprocessors, and authorise an external debugging tool to access, for debugging purposes, only the slave resources assigned to the at least one microprocessor.
