basic of Porting of Micro C/OS-II kernel in ARM powered microcontroller

This Project deals with the porting of Micro C/OS-II kernel in ARM powered microcontroller for the implementation of multitasking and time scheduling. Here a real time kernel is the software that manages the time of a micro controller to ensure that all time critical events are processed as efficiently as possible.

 

We have applied advanced real-time techniques software, that are intensively used in critical areas like space research and defense applications, to realize an industrial real time parameter Monitoring System. The heart of the system is a real-time kernel that uses preemptive scheduling to achieve multitasking on hardware platform. The Arm processor gets all relevant information from one source i.e. the remote terminal section. The temperature analysis data is plotted in convenient diagram in graphical LCD. The trend of all these parameters is available with a granularity of one minute. 

 Fig 1.1: Multitasking

In this project we are going to perform multitasking simultaneously. In Micro C/OS-II maximum number of task is 64, but here we going to perform up to 6 tasks the tasks like LED scrolling, alarm, temperatures sensor, graphical LCD, serial communication, relay are perform simultaneously.

1.1. Existing System

General-computing non-real-time operating systems are often quite non-deterministic. Their services can inject random delays into application software and thus cause slow responsiveness of an application at unexpected times. Other problems in this kind of system are single program approach (one task), power consumption problem.

1.2. Proposed System

In this paper, the proposed method is implemented on a coarse grain reconfigurable architecture with 8 and 32 processing elements. A large amount of random scenario have been simulated and the statistical results presented here clearly show real advantages of the proposed method, but also some limitations drawing the line of future works. The design of embedded systems has become more complex than ever, and the design qualities depend more on the cooperation of multidisciplinary design teams: hardware engineers and software engineers in general.
