Methodology to Enhance the Predictability of I/O Data Exchange Between Device and Tasks

Abstract

Data coming from devices shall be transported to a specific task to be used in a software with the most accurate time and data integrity. During this process, a potential cause for invoking structured hazard and performance degradation is dormant. In this paper, a method %which can protect the situation of possible data corruption which can protect the data integrity from the possible data corruption when collision has happened during I/O data exchange between device and tasks is presented. Also, an example diagram of mechanism according to the method is shown and the effect, merits and demerits of the method is evaluated.
