When it comes to both markets history has shown that reality has often surprised the most optimistic forecasters. We draw on the experience of experts from MIT Berkeley UCLA Worcester Polytechnic Institute INRIA Authentec Radioscape Geovector and Texas Instruments to give a description of some of the important building blocks and implementation choices that combine both technologies in the past and in the future. We highlight different perspectives especially regarding implementation issues in the processing of speech audio video future multimedia and location-based services as well as mobile commerce and security aspects. The book is roughly divided into three sections Chapters describing applications and their implementations on what might be described as today s technology. By this we mean the use of programmable Digital Signal Processors DSPs and ASICs in the manner in which they are being used for today s designs. In these chapters we highlight the applications and the role of programmable DSPs in the implementation. Chapters that present challenges to the current design flow describing new ways of achieving the desired degree of flexibility in a design by means other than programmable DSPs. Whether these new approaches will unseat the programmable DSP from its perch remains to be seen as the commercial value of these approaches is less certain. But they give a detailed overview of the directions researchers are taking to leap beyond the performance curve of the programmable DSP approach. We conclude with a practical yet innovative
