sforms 21.11.1 Esperanto for Devices The principles of Esperanto are applicable for human-to-human and device-to-device com- munication. New functionality in user equipment is often introduced on discrete components. Audio integrated circuits, voice and speech recognition, micropositioning MEMS or GPS integrated circuits are recent examples of new 'real estate' introduced as additional add-in components. This places new demands on packaging and interconnect technology and creates a need for commonality (a common language) both in terms of physical (compatible pin count and connector) and logical (bus architecture) connectivity. The reason for the discrete approach is usually performance and/or risk related. The new function can initially be made to work more efficiently on a discrete IC and engineers responsible for other functional areas feel safer if the new functionality is ring fenced within its own dedicated physical and logical space. Standards initiatives such as the Mobile Industry Processor Initiative are then needed to ensure at least a basic level of compatibility between different vendor solutions. This process is neither particularly efficient nor effective and is generally a consequence of interdiscipline communication issues. 21.11.2 Esperanto for Engineers This in turn is a language problem. Partly this has been solved by the use of English as a common language, though English is neither precise nor efficient. The problem is, however, not just one of spoken language but the descriptive language used. Software engineers speak a different 'language' from hardware engineers, DSP engineers speak a different 'language' from RF engineers, imaging system engineers speak a different 'language' from audio engineers who speak a different 'language' from radio system engineers, who speak a different 'language' from micro- and macropositioning engineers, who speak a different 'language' from mechanical design engineers. Silicon design engineers speak a different 'language' from handset design engineers who sp
