Hardware event handling in the hardware real-time operating systems

An important issue related to Real-Time Operating Systems is the handling of interrupts, timers, mutexes, watchdog timers, synchronization and communication directives as unitary events. In order to obtain a predictable response time for the different types of events that occur simultaneously, it is necessary to have a prioritization mechanism for them. Therefore, this paper proposes a hardware mechanism for handling the events enumerated above, in order to improve the software solution, which is not efficient because it generates delays. The method is implemented in n-tasks Multi Pipeline Register Architecture, that is a microcontroller architecture with Real-Time Operating Systems capabilities implemented in hardware, which allows switching time between tasks of one processor cycle and a response time to events of up to 1.5 processor cycles.
