System on chip (10; 110) comprising: - a plurality of master resources; - a plurality of slave resources; - a plurality of arbitration levels (A 1,..., A N), each arbitration level (A 1,..., A N) being able to control the access of at least one master resource to at least one slave resource, the plurality of arbitration levels (A 1,..., A N) being distributed in hierarchic way between them; each master resource being able to send requests to at least one slave resource according to a bandwidth associated with this slave resource and this master resource, each request transmitting digital data or interrogating the corresponding slave resource, and being transmitted via at least one arbitration level (A 1,..., A N); the system (10; 110) further comprising control means (20; 120) configured to control each bandwidth associated with each slave resource as a function of the capacity of this slave resource to process requests from the master resource corresponding to this bandwidth; each slave resource comprising a buffer memory capable of storing requests to be processed by this slave resource and defining a total capacity for processing requests; each slave resource being able to allocate for each master resource a capacity for processing requests from this master resource as a function of its total capacity for processing requests; the system being characterized in that each slave resource est able to send to the control means a full signal when the processing capacity allocated to a master resource is full. - a plurality of master resources; - a plurality of slave resources; - a plurality of arbitration levels (A 1,..., A N), each arbitration level (A 1,..., A N) being able to control the access of at least one master resource to at least one slave resource, the plurality of arbitration levels (A 1,..., A N) being distributed in hierarchic way between them; each master resource being able to send requests to at least one slave resource according to a bandwidth associated with this slave resource and this master resource, each request transmitting digital data or interrogating the corresponding slave resource, and being transmitted via at least one arbitration level (A 1,..., A N); the system (10; 110) further comprising control means (20; 120) configured to control each bandwidth associated with each slave resource as a function of the capacity of this slave resource to process requests from the master resource corresponding to this bandwidth; each slave resource comprising a buffer memory capable of storing requests to be processed by this slave resource and defining a total capacity for processing requests; each slave resource being able to allocate for each master resource a capacity for processing requests from this master resource as a function of its total capacity for processing requests; the system being characterized in that each slave resource est able to send to the control means a full signal when the processing capacity allocated to a master resource is full. each master resource being able to send requests to at least one slave resource according to a bandwidth associated with this slave resource and this master resource, each request transmitting digital data or interrogating the corresponding slave resource, and being transmitted via at least one arbitration level (A 1,..., A N); the system (10; 110) further comprising control means (20; 120) configured to control each bandwidth associated with each slave resource as a function of the capacity of this slave resource to process requests from the master resource corresponding to this bandwidth; each slave resource comprising a buffer memory capable of storing requests to be processed by this slave resource and defining a total capacity for processing requests; each slave resource being able to allocate for each master resource a capacity for processing requests from this master resource as a function of its total capacity for processing requests; the system being characterized in that each slave resource est able to send to the control means a full signal when the processing capacity allocated to a master resource is full.
