Abstract: Summary form only given. The ability to represent audio and video digitally and its vast popularity poses enormous challenges in protection against unauthorized use, copy and distribution in open, highly uncontrolled Internet environment. Digital watermarking, a technology for insertion of imperceptible information into multimedia content offers a solution for authentication and suitable action thereof. This is a rapidly maturing technology. Initiatives within the industry are ongoing for various forms of multimedia. Technology alone is unlikely to address all the copy protection issues. Business models and legal support also play an important role in tackling them.

Abstract: In this paper, we present an algorithm which automatically maps the IPs/cores onto a generic regular Network on Chip (NoC) architecture such that the total communication energy is minimized At the same time, the performance of the mapped system is guaranteed to satisfy the specified constraints through bandwidth reservation As the main contribution, we first formulate the problem of energy-aware mapping, in a topological sense, and then propose an efficient branch-and-bound algorithm to solve it Experimental results show that the proposed algorithm is very fast and robust, and significant energy savings can be achieved For instance, for a complex video/audio SoC design, on average, 604% energy savings have been observed compared to an ad-hoc implementation

Abstract: As an increasing number of electronic systems are powered by batteries, battery life becomes a primary design consideration. Maxiimizing battery life requires system designers to develop an understanding of the capabilities and limitations of the batteries that power such systems, and to incorporate battery considerations into the system design process. Recent research has shown that, the amount of energy that can be supplied by a given battery varies significantly, depending on how the energy is drawn. Consequently, researchers are attempting to develop new battery-driven approaches to system design, which deliver battery life improvements over and beyond what can be achieved through conventional low-power design techniques. This paper presents an introduction to this emerging area, surveys promising technologies that have been developed for battery modeling and battery-efficient system design, and outlines emerging industry standards for smart battery systems.

Abstract: To date, most Internet applications focus on providing information, interaction, and entertainment for humans. However, with the widespread deployment of networked, intelligent sensor technologies, an Internet of Things (IoT) is steadily evolving, much like the Internet decades ago. In the future, hundreds of billions of smart sensors and devices will interact with one another without human intervention, on a Machine-to-Machine (M2M) basis. They will generate an enormous amount of data at an unprecedented scale and resolution, providing humans with information and control of events and objects even in remote physical environments. The scale of the M2M Internet will be several orders of magnitude larger than the existing Internet, posing serious research challenges. This paper will provide an overview of challenges and opportunities presented by this new paradigm.

Abstract: NAND-flash-based SSDs (solid-state disks) are recently used in embedded computers to replace power-hungry disks. This paper presents a hybrid approach to large SSDs, which combines MLC flash and SLC flash. The idea is to complement the drawbacks of the two kinds of NAND flash with each other's advantages. The technical issues of the design of a hybrid SSD pertain to data placement and wear leveling over heterogeneous NAND flash. Our experimental results show that, by adding a 256 MB SLC flash to a 20 GB MLC-flash array, the hybrid SSD improves over a conventional SSD by 4.85 times in terms of average response. The average throughput and energy consumption are improved by 17 % and 14%, respectively. The hybrid SSD is only 2% more expensive than a purely MLC-flash-based SSD, for which the extra cost is limited and very rewarded.
