Hello everyone, I am Jide Cheng. This article discusses the DPPM function of charging chips, which stands for Dynamic Power Path Management. DPPM is the full name of Dynamic Power Path Management. Have you ever thought about a question: when your phone runs out of battery and shuts down, you want to charge it while … Read more
Article Overview Today, this article mainly discusses how the commonly used DVFS method in the industry reduces power consumption, what type of power consumption is reduced, and why it can lower power consumption. Main Purpose Currently, under advanced processes, different chip manufacturers are pursuing low-power chip design for various reasons. Some manufacturers have certain requirements … Read more
1. Concept Composition of Power Consumption: Three main sources of power consumption: surge, static power, and dynamic power; Surge Current: Refers to the maximum instantaneous input current generated when the device is powered on, known as the inrush current; The surge current is device-dependent; Surge power is not our primary concern, so it is only … 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
Low Power Design 5.1 Power Consumption Sources Surge、Static Power Consumption and Dynamic Power Consumption are the three main sources of power consumption. • Surge current refers to the maximum instantaneous input current generated when the device is powered on, and is also known as startup current in applications. • Standby current refers to the current … Read more

1.5 The Conflict Between Dynamic Power and Static Power Over the past 15 years, with the development of semiconductor technology, Vdd has decreased from 5V to 3.3V, and from 2.5V to 1.2V. The ITRS roadmap predicts that high-performance devices will use 1.0V in 2008 and 2009, while low-power devices will use 0.8V. The issue with … Read more
In power-off modules, it may be required for the register to latch data before power-off or to restore latched data after power-on, which necessitates a special unit known as the Retention Register. The retention register consists of two sets of registers: the Main Register and the shadow register, where the shadow register is powered by … Read more
