Prototyping distributed embedded operating system for NoC architecture

摘要

In this paper, we propose a light-weighted embedded OS (EOS) for 8051 microcontrollers used in NoC. This EOS is developed in such way that it is able to be extended as a distributed OS for NoC. Along with the development of the NoC, an operating system is demanded for managing resources and task execution flow in computing systems based on NoC architecture. To build the EOS suitable for small C51 core, the model of the EOS is built and discussed first in this paper. With the model, the structure of the EOS mainly involves multi-task management and inter-task communication. Then we verify the model. By reserve interfaces, the tasks in distributed EOS are expected to communication with each other among NoC system via routers.
