Resumo
© 2023, Brazilian Microelectronics Society. All rights reserved.This work studies the impact in the parallel processing of the Interlocked-Hardware-Microkernel (IHM) Plasma microprocessor (IHM-Plasma) by implementing the Earliest-Deadline-First (EDF) algorithm by hardware in the task-scheduler block that belongs to those task-based operational systems, such as that related to the real-time operational systems (RTOS). IHM-Plasma presents Reduced Instruction Set Computer (RISC) architecture. Results show that the EDF algorithm running in IHM-Plasma's hardware has increased the number of tasks executed per second by up to 174% compared to the same algorithm running in software. The developed work has great potential use in Hard Real-Time Systems and others where a rigid control of deadlines is essential and hold many tasks.
