Low Power Design Techniques: Data Gating (Data Gating) and Operand Isolation (Operand Isolation) Previously, we discussed Clock Gating (Clock Gating), which is a well-known low power design technique. It can be easily applied during the logic synthesis stage without requiring changes to the RTL, making it one of the more straightforward methods for achieving low … 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
Low Power Design in C++ Embedded Development In modern embedded systems, low power design is a crucial topic. With the proliferation of IoT devices and wearables, effectively managing power consumption has become a challenge that developers must face. This article will introduce some low power design strategies in C++ embedded development and provide corresponding code … Read more
In today’s rapidly developing smart health device market, blood pressure monitors are no longer just simple “measuring tools”; they have become the “smart steward” of family health. However, a truly reliable, user-friendly, and feature-rich blood pressure monitor relies on a powerful “core chip”. Today, we unveil the hardcore capabilities of the medical-grade chip WT2801 – … 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
What are Always-On Logic Cells? Some logic needs to remain active during shutdown, such as Power Switch Cells, Retention Register Cells, and Isolation Cells. These are referred to as Always-On Logic Cells. They can maintain a constant ‘on’ state regardless of whether the voltage area is powered down. Always-On Logic Cell Where are they used? … 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
Click the blue text to follow us Add a star to the “…” in the top right corner of the homepage to stay updated! As circuit and system design sizes shrink, it becomes increasingly challenging for engineers to select suitable components for their designs. In many different applications (such as earbuds, thermometers, wearable devices, styluses, … Read more
The Development Status and Advantages of Domestic FPGAs In recent years, the development of domestic FPGAs has been rapid, with a total of 22 FPGA manufacturers in China (19 excluding those for special purposes). Major companies include Unisoc, Anlogic, and Fudan Microelectronics. In terms of market share, the total revenue of major domestic FPGA design … Read more
Concept of Low Power In the design of embedded systems, low power design is a challenge that many designers must face. This is because embedded systems are widely used in portable and mobile products, which often do not have a constant power supply and rely on batteries for power. Therefore, designers consider every detail to … Read more
