Title:
PROCESSOR-SIMULATION METHOD USING A MODEL COMPRISING A SET OF OBJECTS
Document Type and Number:
WIPO Patent Application WO2006084845
Kind Code:
A3
Abstract:
The invention relates to a method of simulating a complex system including a scheduler hierarchy and to the corresponding storage means and computer program product. More specifically, the invention relates to a method of simulating a complex system comprising at least one processor that executes a set of functions under the control of a hierarchical group of schedulers. According to the invention, the method includes a step (21) consisting in constructing an architectural model of the complex system comprising a hierarchical group of components, each of said components comprising an instance of an object class belonging to the group containing: a first class, known as the Processor class, which represents an abstract model of any processor included in the complex system, each instance of the Processor class being referred to as a modelled processor; a second class, known as the Function class, which represents an abstract model of any function executed by the complex system, each instance of the Function class being referred to as a modelled function; and a third class, known as the Scheduler class, which represents an abstract model of any scheduler included in the complex system, each instance of the Scheduler class being referred to as a modelled scheduler and being used to manage the components, modelled function(s) and/or other modelled scheduler(s) contained therein. Each instance is initialised with at least one attribute that characterises the behaviour desired therefrom.
