DRMS Co-design by F4MS

Abstract: In this paper, we present Digital Rights Management systems (DRMS) which are becoming more and more complex due to technology revolution in relation with telecommunication networks, multimedia applications and the reading equipments (Mobile Phone, IPhone, PDA, DVD Player,..). The complexity of the DRMS, involves the use of new tools and methodologies that support software components and hardware components coupled design. The traditional systems design approach has been somewhat hardware first in that the software components are designed after the hardware has been designed and prototyped. This leaves little flexibility in evaluating different design options and hardware-software mappings. The key of codesign is to avoid isolation between hardware and software designs to proceed in parallel, with feedback and interaction between the two as the design progresses, in order to achieve high quality designs with a reduced design time. In this paper, we present the F4MS (Framework for Mixed Systems) which is a unified framework for software and hardware design environment, simulation and aided execution of mixed systems. To illustrate this work we propose an implementation of DRMS business model based on F4MS framework.
