스마트 TV용 고속 IO 기법

Abstract

Smart TV composes data structure of tree form through data conversion process to use XML form files. Data with tree form exist in heap area of process address space in which it is eliminated at the same time as process abortion. Therefore even if data in tree form is composed through conversion process, tree form data must be composed through another conversion process to use XML files when rerunning the process. This study presents a technique for rerunning without data conversion by adding persistency in tree form data in smart TV environment. Fast IO technique provides object to add persistency in part of process address space. The data structure gains persistency by saving the tree form data in object and can be reused again without data process even after rerunning the process. Fast IO technique was applied in the web browser to parse HTML and skip the process of composing tree. Running time was reduced to up to 61% in CPU, memory, SSD environment.
