In terms of Ethernet interface connections, there are usually two solutions: one is when the terminal product has a system running, such as Android systems on chips like RK3399, Linux systems on chips like i.MX6, and RTOS systems on low-end ARM chips like STM32F107. These chips have integrated Ethernet MACs, and by adding simple PHY … Read more
1. The Concept of “Memory Alignment” Memory alignment, also known as byte alignment, is an attribute of the memory address where a data type can be stored. This attribute is essentially the memory address itself, which must conform to certain specifications. This specification states that the memory address value must be a power of 2. … Read more

This Issue’s Special Recommendations This issue recommends a special topic on security technology, covering learning about the ShanHai security processor from Arm, learning about Arm TrustZone technology (including interrupts), Arm PSA technical materials, privacy computing, information and functional … Read more
Instruction sets can be divided into Complex Instruction Set Computing (CISC) and Reduced Instruction Set Computing (RISC), represented by the architectures x86, ARM, and MIPS. ARM RISC is a chip architecture designed to improve processor speed, with key technology in pipelining, which allows multiple instructions to be completed in one clock cycle. Compared to Complex … Read more
Author: Huang Yefeng Original from EET Electronic Engineering Magazine Processors based on the RISC-V architecture are increasingly appearing in everyday electronic products, becoming more commonplace: not only have some typical MCU manufacturers begun to embrace RISC-V, such as the previously interviewed Tsinghua Unigroup, but also companies like GigaDevice have launched RISC-V product lines; Moreover, this … Read more
During the China-US trade war, Chinese companies were concentrated in a chokehold in the chip field. This time, Tangxun Information Academy has launched a series of articles analyzing companies in the chip industry for discussion and learning. The British company ARM is a global leader in semiconductor intellectual property (IP) provision. More than 95% of … Read more
Source: Eefocus Original Author: Liu Haoran Introduction ✦ The main gap between RISC-V and ARM currently lies in the upstream and downstream industrial ecosystem and large-scale applications, which is the biggest challenge and difficulty facing the players in the RISC-V camp. ✦ ✦ We command computers to work, and we cannot simply say to the … Read more
Recently, Zhiqu Dog introduced ARM’s brand new Cortex-A75 and Cortex-A55 architectures, as well as the Mali-G72 GPU (see “ARM’s Breakthrough! Mobile Processors Will Transform in a Few Months Because of Them!”). However, the article involved a lot of technical terms, and some readers commented that they found it “hard to understand.” No worries, ARM’s designers … Read more
The Cortex A77 architecture, newly launched by Arm in May 2019, utilizes TSMC’s 7nm process with a peak frequency of 3GHz, achieving a 20% performance improvement. A previous article introduced the architecture of the strongest X86 processor, ZEN, which can be found here. This article analyzes the strongest Arm processor, A77, based on the same … Read more
