Source: Semiconductor Industry Observation Original Author: Gong Jiajia More than twenty years ago, Microsoft’s Windows operating system and Intel’s X86 chips formed a “duopoly” that dominated the computer market until they encountered Apple. Apple’s rise caused cracks in the once unbreakable Wintel alliance, and “Windows + X86” was no longer the only option; you could … Read more
When it comes to chip manufacturers, who do you think of first? Intel, AMD, Apple, Samsung, Qualcomm, MediaTek, Kirin… In fact, except for a few chip manufacturers like Intel and AMD that are involved in the “X86 circle,” the rest rely on ARM for their business. The Two Meanings of ARM The term “ARM” has … Read more
The rapid development of Internet technology has made embedded engineers popular talents. The Internet of Things Era — A New Era in the Embedded Field Since the 1970s, embedded systems have developed for over thirty years. In recent years, with the advancements in computer technology, communication technology, software technology, and Internet technology, embedded systems have … Read more
1. The Engineer’s Perspective on “Embedded Systems” From an engineer’s point of view: focus on understanding the concept of “embedding” from three main aspects: 1. From the hardware perspective, integrating peripheral devices based on the CPU into the CPU chip itself. For example, early computers based on the X86 architecture only had arithmetic and accumulator … Read more
