Abstract
The key requirements for program applications providing robot control systems operation are requirements of the warranty of the on-time execution of functions being realized by these systems. An application density that is the maximum achievable quota of processor payloads from application programs is used as the application execution efficiency criterion. A value of the application density depends not only on a composition of the tasks and intertask communications but also on a choice of the combination of system services, i.e. a scheduling discipline and an access protocol to the sharable system resources. The paper presents a suggested method for the application verification on a possibility of usage of the most efficient combinations of system services as well as examples of the efficiency estimation based on simulation modeling of the execution of program applications.
