Design and Implementation of Flash I/O Software in Embedded System Cheng Quanzhou1 Zhang Li1 Feng Xiang2 (1.Computer Science Department in Nanyang Normal University, Nanyang 473000 2.College of Computer and Communication in Hunan University, Changsha 410082 ) Abstract: Flash memory is the most common memory used in embedded system, so the management and access technology of flash memory have great effects on performance of the whole system. At present, most flash management software adopted in embedded system, however, are insufficient in portability and agility. So this article proposes a more rational layered architecture of flash I/O software on the base of the analysis of current problem and at last proves that this architecture has some advantage in terms of portability and universality by its modular design and implementation.
