Holzer B. Knerr P Belanovic and M. Rupp Institute for Communications and Radio Frequency Engineering Vienna University of Technology Gu hausstra e 25 389 1040 Vienna Austria Received 1 December 2005 Revised 11 April 2006 Accepted 24 April 2006 Nowadays design of embedded systems is confronted with complex signal processing algorithms and a multitude of computational intensive multimedia applications while time to product launch has been extremely reduced. Especially in the wireless domain those challenges are stacked with tough requirements on power consumption and chip size. Unfortunately design productivity did not undergo a similar progression and therefore fails to cope with the heterogeneity of modern architectures. Electronic design automation tools exhibit deep gaps in the design flow like high-level characterization of algorithms floating-point to fixed-point conversion hardware software partitioning and virtual prototyping. This tutorial paper surveys several promising approaches to solve the widespread design problems in this field. An overview over consistent design methodologies that establish a framework for connecting the different design tasks is given. This is followed by a discussion of solutions for the integrated automation of specific design tasks. Copyright 2006 M. Holzer et al.

INTRODUCTION Over the past 25 years the field of wireless communications has experienced a rampant growth in both popularity and complexity. It is expected that the global number of mobile subscribers will reach more than three billion in the year 2008 1 . Also the .
