ABSTRACT
Coarse-grained reconfigurable architectures are considered appropriate for embedded systems because they can satisfy both flexibility and high performance requirements. However, power consumption is also crucial for the reconfigurable architecture to be used as a competitive processing core in embedded systems. This chapter shows breakdown of power consumption in CGRA for two cases-the base CGRA mentioned in Chapter 4 and ADRES [60]. Based on the power analysis results, we describe which component of CGRA consumes dominant power and why power consumption has been a serious concern for reliability of CGRA-based embedded systems.
