1.2 Background

Introduction to conventional wisdom has it that communication bandwidth will limit the viability of streaming video applications on wireless terminal devices like cellular telephones, smartphones, personal digital assistants (PDAs) and even compact laptop computers. Even if unlimited wireless bandwidth were suddenly to become available, service providers and terminal device manufacturers would have no assurance they could provide a high-quality streaming video experience, unless the architecture of the terminal device featured a solid foundation for the application and the processing capabilities to pull it off. To be able to cope with the demands of a streaming video application and the vagaries of wireless communication in general, a terminal device must have a unique blend of hardware and software especially well-suited to wireless streaming video [0].

1.2 Research Problem:

Fortunately, this dual-processor architecture is very well suited to wireless streaming video. Because of the strenuous demands of applications like streaming video, a partitioning of the application's tasks between the two processors is critical for several reasons. And second, assigning tasks to the appropriate processor will reduce the number of processor cycles required for each task, which, in turn, reduces the power drained from the battery and extends the usable life of the mobile device.

1.3 Aim and Objective:

Using mathematic formula-in order to achieve an optimal balance between power and performance, we introduce a notion of “Utility Factor UF” for a system, and try to optimize the UF for the system. UF
