Industrial applications require meeting real-time specifications. Real-time systems are implemented using processors in order to execute real-time tasks. Temporal constraints must be supported by real-time operating systems or designing the application based on specific hardware resources. Previous approaches to real-time processors have implemented operating system functions in hardware and consequently they are designed to manage tasks’ periods rather than real-time. They cannot be used in a great deal of applications because they are based on restrictive models. This paper proposes the Hardware Real-Time Scheduling Architecture (HRTSA) that introduces an innovative methodology with which to efficiently manage time, events, priorities and tasks in an embedded hardware implementation. The HRTSA is described and real-time performance is evaluated
