摘要

摘要——本工作通过在属于基于任务的操作系统（如与实时操作系统（RTOS）相关的操作系统）的任务调度器块中用硬件实现最早截止日期优先（EDF）算法，研究了互锁硬件微内核（IHM）Plasma微处理器（IHM-Plasma）并行处理中的影响。IHM Plasma提出了精简指令集计算机（RISC）体系结构。本研究观察到的主要结果表明，与通过软件运行EDF算法的原始Plasma相比，在运行具有14个活动任务的基于任务的操作系统时，通过硬件运行EDF的IHM Plasma将每秒执行的任务增加了174%。所开发的工作在硬实时系统和其他系统中有很大的潜在用途，在这些系统中，严格控制截止日期是必不可少的，并包含许多任务。

Impact in the Parallel Processing of IHM-Plasma Using the Earliest-Deadline-First Algorithm for the Task-Scheduler Realized by Hardware

Abstract—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. The main results have observed by this study show that the IHM-Plasma running the EDF algorithm by hardware has increased the tasks executed per second in 174% while running a task-based operational system with 14 active tasks in comparison to the original Plasma running the EDF algorithm by 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.

期刊介绍： This journal will present state-of-art papers on Integrated Circuits and Systems. It is an effort of both Brazilian Microelectronics Society - SBMicro and Brazilian Computer Society - SBC to create a new scientific journal covering Process and Materials, Device and Characterization, Design, Test and CAD of Integrated Circuits and Systems. The Journal of Integrated Circuits and Systems is published through Special Issues on subjects to be defined by the Editorial Board. Special issues will publish selected papers from both Brazilian Societies annual conferences, SBCCI - Symposium on Integrated Circuits and Systems and SBMicro - Symposium on Microelectronics Technology and Devices.
