The technologies discussed in the previous chapter are mature. Engineers have been using them for some time, and design tools have supported them for many years. In this chapter, we begin to discuss more recent and proactive methods to reduce power: power gating and adaptive voltage scaling, these two techniques. Both of these techniques differ … Read more
Low Power Design Methods – Frequency and Voltage Scaling The practical operational space of circuit design lies in the process, design goals, process libraries, and timing analysis methods. Under special processes, temperature inversion particularly limits the range of timing, voltage, and temperature to maintain their normal monotonic relationship. A detailed analysis of all these factors … Read more
1.1 Overview Over the past two decades, the design of complex chips has undergone a series of transformations. In the 1980s, language-based circuit design and synthesis emerged. In the 1990s, design reuse and IP became mainstream design practices. In recent years, low power design has begun to change the way designers handle complex SoC designs … Read more
