Abstract This article briefly describes the main classifications and sources of power consumption in embedded systems, as well as how to achieve low power design from both software and hardware perspectives. The low power design methods mentioned in this article are relatively simple, as the most critical parts of instruction cache and data cache are … Read more
This article elaborates on the core components and importance of the clock system in microcontrollers (MCUs). It points out that the performance and power consumption of an MCU fundamentally depend on its clock system. This system is based on a clock source (external crystal oscillator or internal RC oscillator) and distributes signals to various modules … Read more

Brothers in the backend, contact me. I have plenty of space at home and I’m not afraid of taking up space. I want to build a stable multi-bay NAS at the server level. The requirements are low cost and many bays. If you want to talk about this, then I think you must use the … Read more
The USB interface, with its plug-and-play versatility and strong compatibility, has almost become the connection bridge for all electronic devices, from keyboards and mice to external hard drives and webcams. However, almost all high-resolution cameras use the MIPI interface instead of the convenient USB. Wouldn’t it be easier to connect all peripherals through a HUB … Read more
MCU (Microcontroller Unit) and MPU (Microprocessor Unit) are the core chips of embedded systems, but they have significant differences in design goals, architecture, and application scenarios. The main differences are as follows: 1. Core Design Philosophy MCU (Microcontroller Unit) Integrated System on Chip: Integrates CPU, memory (RAM/Flash), and peripherals (GPIO, ADC, UART, etc.) all on … Read more
Some may have noticed that the voltage standards for microcontrollers vary; some operate at 3.3V while others use 5V. Why isn’t there a unified standard? Is this a historical legacy issue or an inevitable result of technological evolution? Today, we will explore this question. 1. The Aftermath of the TTL and CMOS ‘Cold War’ The … Read more
In today’s rapidly developing information technology era, integrated circuits, as the core components of electronic devices, are of paramount importance. Among the various types of integrated circuits, ASICs (Application-Specific Integrated Circuits) are increasingly becoming the preferred solution for high-end electronic products due to their outstanding performance and efficiency. ASICs are integrated circuits designed specifically for … Read more
