Abstract :
To use the XML file, it must be converted into a tree structure form in smart TV application. However, when the application is terminated, tree are eliminated in process address space. When application is restarted, XML file need to be converted to tree again in order to execute application. This study presents a Fast I/O technique that enables restarting a application without data conversion process by adding persistency in tree in a smart TV environment. Fast I/O technique provides an object, in which the tree are saved adding persistency in process address space. The data structure gains persistency by saving the tree in an object and reusing it without data conversion when restarting the application. Fast I/O technique was applied in the web browser to parse HTML and skip the process of composing a tree. Running time was reduced up to 61% in the test environment, consisting of CPU, memory, and an SSD.
