Research and implementation on the embedded system for Object-Oriented cooperative scheduler

In this paper, a unit designed for purpose data programming to multi serial DataFlashs has been proposed. In hardware, it is composed of one MCU(Micro Control Unit) and multi serial DataFlashs connected to MCU by SPI interface which result to easy design and save GPIOs; in software, an Object-Oriented cooperative scheduler is applied and runs on the microcontroller, and a communication software used to provide data by USB connection runs on the computer. In order to program the data which in the purpose file to multi serial DataFlashs fast and correctly, the strategies that how to program multi serial DataFlashs is extremely important. The results of performance evaluations show that an Object-Oriented cooperative scheduler can deal with multi serial DataFlashs programming efficiently. It is improved the efficiency and reusability and decreased the complexity of the software.
