embedded systems. In our routine, embedded systems are widely used these days. Embedded<br />
systems have developed since a computer has invented and extended. However, in recent<br />
years, much <strong>at</strong>tention has been given to the embedded systems because it is becoming<br />
complic<strong>at</strong>ed. In other words, the technology of semiconductor and network has evolved<br />
rapidly. In addition, the technology of software was developed a lot such as multimedia and<br />
internet technology, etc. For example, the smartphone have started various works th<strong>at</strong> are<br />
music player, movie player, game and internet, etc. as more than a simple message transfer<br />
function. The various functions have increased embedded systems complexity [9]. In the past,<br />
embedded systems were simple hardware. However, nowadays embedded systems hardware<br />
increased complexity by advanced hardware and many needs of users. Along with advanced
