The necessity for more affordable, portable and flexible electronic devices is driving todays embedded engineers to think carefully about new ways to cut costs and produce more malleable designs. With this need in mind, many successful developers have begun to migrate system functionality formerly implemented in costly and monolithic custom hardware, to software. As an effect of this trend, the measurement and optimization of embedded software has becoming increasingly important. This book is the first reference to teach readers how to migrate embedded hardware functions to software, how to measure the effectiveness of the resulting embedded software, and how to optimize it in order to maximize system performance overall.
