Abstract

The invention relates to a data processing method in a network on chip formed of a plurality of resources (310,320) capable of communicating with one another and of processing and at least one network controller (300) capable of initialising the communications in the network by initialisation of a credit system, the process comprising at least one communication step between at least one first resource (310) and at least one second resource (320), said communication step comprising: at least one emission by the first resource of a first plurality of special data or “credits” destined for the second resource, at least one receipt by the first resource of a first plurality of data to process sent by the second resource, the emission by the second data resource destined for first resource being authorised following the receipt by the second resource of credits emitted by the first resource.

Claims26

Dependent claims

Data processing method in a network on chip formed of a plurality of elements or “resources” (310,320,330,340,350) capable of communicating between one another and of processing, and at least one element or “network controller” (300) capable of initialising the communications in the network, the method comprising:

the receipt and storage in memory by one or more resources, one or more programs or “credit management configurations” sent by the network controller,
at least one first communications step between at least one first resource (310) and at least one second resource (320), said communication step comprising:
a) at least one emission by the first resource (310) of a first plurality of special data or “credits” destined for the second resource (320), the destination of the credits emitted by the first resource (310) being defined in a common credit management configuration that the first resource uses, the common credit management configuration being selected from one or more different credit management configurations stored in the memory of the first resource,
b) at least one receipt by the first resource (310) of a first plurality of data to process sent by the second resource (320), this emission of data to be processed sent by the second data resource to the first resource being authorised following the receipt by the second resource of credits emitted by the first resource.

1 more element

Network on chip device comprising at least one element or “resource” capable of communicating with one or several resources of the network and capable of carrying out at least one data processing operation, said resource comprising means forming an interface with the network, means forming an interface with the network comprising:

means for emitting special data or “credits” capable of emitting credits to one or more resources of the network, the destination of the credits being emitted by the credit emission means depending on a type of programming or configuration called credit management,
means for receiving credits, capable of receiving credits from one or more resources of the network,
means for emitting data, to process, capable of emitting data to process to one or more resources of the network,
means for receiving data capable of receiving data to process from one or more resources of the network,
means forming an interface with the network comprising among others:
means for authorising the emission by said data emission means, of data to process to at least one first resource of said other resources of the network following the receipt, by said credit receiving means, of credits from said first resource,
storage means capable of storing several different credit management configurations,
means for selecting a configuration capable of selecting at least one common credit management configuration from the several different credit management configurations.
