Method and circuit arrangement for temporally limiting and separately accessing a system on a chip

Abstract

A circuit arrangement and method for temporally limiting and separating access between at least one master unit and at least one slave unit via a network-on-a-chip bus system in a system-on-a-chip, wherein the access between the at least one master and slave units is implemented via communication paths defined by bus interfaces, where within the circuit arrangement, the network-on-a-chip bus system is expanded by an adaptation unit that includes an access manager and a complementary logic for the bus interfaces, where the adaptation unit and the bus interfaces are then controlled by the access manager via the complementary logic using a communication plan such that access between the master and slave units via the communication paths specified by bus interfaces is performed in accordance with the temporal requirements of the communication plan so that time-controlled systems can be implemented simply using commercially obtainable standard bus systems.
