Electronic system having increased coupling by using horizontal and vertical communication channels
An electronic system supports superior coupling by implementing a communication mechanism that provides at least for horizontal communication for example, on the basis of wired and/or wireless communication channels, in the system. Hence, by enhancing vertical and horizontal communication capabilities in the electronic system, a reduced overall size may be achieved, while nevertheless reducing complexity in printed circuit boards coupled to the electronic system. In this manner, overall manufacturing costs and reliability of complex electronic systems may be enhanced.
