The MSP430 microcontroller is a microcontroller launched by Texas Instruments (TI) in 1996. It is a 16-bit ultra-low-power microcontroller with a Reduced Instruction Set Computing (RISC) architecture. However, many beginners are not very familiar with the MSP430 compared to other microcontrollers like the 51 and STM32. Below, we will explain the MSP430 microcontroller, hoping to … Read more
When it comes to processor architectures, the most well-known globally are ARM, X86, and PowerPC. As a result, many people often compare them, yet there are still many who are unclear about their differences. Below, we will compare them from multiple aspects to help you understand the differences between ARM, X86, and PowerPC at once! … Read more
Unlike independent brands like Intel or AMD, ARM-designed processors may not be known by many users, but few would think that processors designed by ARM exist in over 130 billion different devices. This includes smartphones, gaming consoles, smartwatches, and even in hygrometers, ATMs, and countless other devices. Moreover, in 2020, these ARM-based processors also made … Read more
With little knowledge of hardware, let’s learn from Master Yang’s article “Do You Understand ARM CPU Architecture?!”. Introduction Recently, there was a requirement to install MySQL 8.0 on an ARM architecture; I’ve heard of ARM CPUs, but have never deployed them in practice; and what exactly is this ARM CPU architecture? I only have a … 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
Currently,X86 and ARM architectures are recognized as the two most outstanding architectures in the commercialization process. Previously, we introduced the X86 architecture, and today we will introduce another architecture that has been on fire for nearly a decade, ARM. ARM architecture, formerly known as Advanced RISC Machine (earlier known as: Acorn RISC Machine), is a … Read more
