In the design of CPU cores, SIMD (Single Instruction Multiple Data) is a commonly used data parallel processing method that operates on multiple data elements simultaneously through a single instruction to enhance the computational efficiency and speed of the processor. SIMD has a wide range of applications, such as image processing, scientific computing, encryption and … Read more
May. Click the blue text to follow us 2025.05 In May 2010, Andrew Waterman, a student at the University of California, Berkeley, sent an email to his professors. After experimenting with various teaching methods for a three-month project, he concluded: They should revive the dying microprocessor architecture DEC Alpha. “I don’t see what new things … Read more
This article is the second in a series discussing peripheral modules of microcontrollers, focusing on how to improve ADC conversion accuracy.In this article, I will summarize the understanding of the reference voltage for ADCs, which many engineers are not very clear about, especially in scenarios where the ADC is used with a battery directly powering … Read more

In mid-May, a notice circulated regarding a major MCU manufacturer criticizing agents and sales for violating regulations by selling at high prices in the open market. MCU, short for Microcontroller Unit, is a microcomputer. It is small, with an ordinary MCU being about the size of a fifty-cent coin; it is inexpensive, with prices ranging … Read more
1. Introduction In previous articles, we developed applications that were embedded into the kernel within initramfs. Each time we needed to change the application, recompiling the kernel was cumbersome. Now, we will port lrzsz to enable file import and export via the serial port, making it easier to update applications by importing them into the … Read more
