In this work we introduce a new type of SmartPhone: a bi-processor SmartPhone equipped with a network interface GSM/GPRS/EDGE/UMTS. The architecture used, with two processors, is introduced to take advantage from the subdivision of the functionalities realized through the two processors. This results in a better distribution of different functions, all above when multi-media traffic is considered. Moreover the interaction between the two processors has to be realized in a convenient manner to better take advantage from the sub-division. The form of communication established between the two processors we have chosen is the serial communication based on the standard RS232. Before to realize the product we propose to evaluate the performance of a similar project. To do this last we built a simulator focusing our attention on the communication between the two processors and we generated different types of data traffic (voice call, sms, etc.). Furthermore we considered GPRS connections on our simulator to verify that a similar architecture, when correctly developed and dimensioned, can support this type of data traffic.
