Abstract

In real time systems, the accuracy of the system's behavior depends on the results of calculations and generated time. One of the biggest challenges of these systems is tasks scheduling according to their deadline. Scheduling issues have complex and sometimes inconsistent conditions, as a result, the system must correctly respond the intended answer within the specific deadline. Industrial control systems, medical, controlled rockets, satellites and so on are of this category. An optimum allocation of tasks in real time multiprocessor systems, often referred to non-deterministic polynomial hard problem. Intelligent methods are used to solve such problems. Data collection in this paper consists of three categories and it is composed of 100 tasks that is implemented in Java language in Eclipse environment. In this paper, the tasks scheduling of real time multiprocessor systems in real time using multi-purpose genetic algorithms for doing tasks and deadlines was studied that this algorithm is optimized to the uniform rate scheduling algorithms.
