  • Execution model for real-time server object
    Babau, J. Ph. ...
    The goal of this paper is to find the most efficient architecture for distributed and adaptive systems that could provide services, which have to be executed within a given time frame. A real-time ... client/server architecture is proposed; this paper will focus on the server part of the architecture: the Real-Time Server Object (RTSO). Within this architecture, a client communicates with a local proxy object, which acts as a representative of one remote RTSO. The software architecture for a RTSO is based upon a reflective architecture. A metaobject controls the application and one object provides the services issued from the client request, which include some real-time constraints. The hardware architecture for a RTSO is a multiprocessor architecture in which processors are dedicated to the metaobject and the object respectively. Within the same server site, a metaobject (function and data members) is mapped onto dedicated processors named kernel processors; the methods (function members) are mapped onto task processors. Depending on their use, the attributes (data members) are mapped onto task, kernel processors or onto a real-time shared memory. Finally, the real time temporal performance of such a complex architecture is evaluated.
