Hardware Implementation of a Real-time Operating System

Design of a Hardware Multiprocessor Real-Time Operating System

We propose a single Hardware RTOS (Real-Time Operation System) which can manage a number of processors with main services. The validation has been achieved by the implementation of the HwRTOS on a VirtexII Pro platform included two PowerPC.

A Hardware-Software Real-Time Operating System Framework for SoCs

with reconfigurable logic and multiple processing elements sharing a common memory, like that shown in Figure 1, is likely to become quite common in the near future. For example, programmable-logic companies are producing single chips containing millions of reconfigurable logic gate equivalents and full-custom VLSI processors. Designers can customize such chips by reprogramming the reconfigurab...

Implementation of Timed Automata in a Real - time Operating System

VLSI implementation of a real-time operating system

| This paper proposes a new approach to realize a very high performance real-time OS using VLSI technology. In order to con rm the e ectiveness of this method, the most basic system calls have been designed. According to the evaluation results based on a gate array implementation, hardware portion of system calls can be executed within 4 clocks and the task scheduler can be performed in only 8 ...

Real Time Operating Systems Implemented in Hardware

This paper describes several state-of-the-art realtime operating systems (RTOS) implemented in hardware that implement task scheduling, synchronization, multiprocessor dispatching, time management and event management. When designers develop RTOS support in hardware different levels of hardware usage are used. Many architects developing RTOS supporting hardware are opting for designs focused ar...
