Abstract :
This paper describes the modeling of a mobile terminal system containing a run-time configurable transform unit specified in a hardware description language. This transform unit can perform two of the most commonly utilized trigonometric transforms: the fast Fourier transform (FFT) and inverse discrete cosine transform (IDCT). A wireless ATM network model was implemented to demonstrate how these transforms are scheduled in the terminal. Due to the dynamic reconfiguration, it was necessary to create a number of asynchronous models to successfully embed the synchronous hardware model into a dataflow simulation. Scheduling of the transforms in the terminal system is presented and the dataflow block diagram incorporating the hardware model is studied in detail
