Analysis of Real-Time Applications Feasibility through Simulation
An approach to estimate feasibility of a real-time multi-task application with various combinations of the scheduling mode and the protocol of access to shared informational resources when run on a multi-core platform is described. The application structure is specified through a simple formalized pr...

The approach is based on the notion of application density introduced by the authors, which characterizes the use of computational resource by this application and is derived from estimation of the application feasibility for various values of processor performance and the number of its cores in case of a multi-core platform. The overall structure of a simulation tool for estimation of the task response time (and therefore, application feasibility) is described, which provides more exact data compared to the known analytical methods where they are applicable.
