A Method for Mobile Terminal Platform Architecture Development

We introduce a novel architecture, called the Network-on-Terminal Architecture (NoTA), for mobile terminal platforms. This paper concentrates on the platform development and validation flow adopted for NoTA. Platform requirements are expressed as use cases that are modelled using UML2 with Telelogic’s Tau G2 tool. Models are executable so that use case behaviour can be animated. Use cases are used as test cases in the platform architecture development for which use case information is transferred as execution traces. We use CoFluent Studio tool for platform architecture specification and performance analysis. The use case execution trace is fed into a functional model that represents the computation load. NoTA is service oriented and thus the functional model consists of platform services. The computation and communication resources are modelled with a separate platform architecture model. The tool allows exploring different configurations and allocations of the functional and platform models quickly and provides extensive performance information, including power consumption.
