Intel and Arm Diversify Their Focus at Computex 2018

We have traditionally viewed Intel and Arm as the dominant players in the PC and server markets, and the mobile application domain, respectively. Although these companies have attempted to cross into each other's territories in the past, they have not been particularly successful. However, at the 2018 Computex conference, "diversification" became the main theme.Traditionally, Intel is a major player in the PC and server solutions market, but this time it did not focus much on these two primary products. Instead, it showcased exciting developments in quantum computing and cloud AI solutions that were not publicly displayed.On the other hand, Arm has deviated from its previous focus. Prior to Computex, it had already announced new architectures, but these architectures are not

The Turbulent Future of Arm: Can RISC-V Take on the Challenge?

According to reports from Electronic Enthusiasts Network (by Zhou Kaiyang), there have been numerous reports claiming that Nvidia's exclusive acquisition negotiations for Arm have entered the final stages, with related parties stating that the transaction could be completed as early as late summer this year. As an architecture that supplies billions of chips to the market each year, this news has raised concerns about Arm's position, and its open-source competitor RISC-V has begun to emerge in people's minds.As the dominant player in the mobile processor market, Arm is currently the mainstream RISC architecture. While Intel has triumphed in the PC sector with its CISC architecture, Apple’s shift of its Mac product line to Arm processors means Intel is about to

The Rise of ARM Chips: A Game Changer in the Semiconductor Industry

Since its official establishment in 1990, ARM has continuously made breakthroughs in the field of 32-bit RISC (Reduced Instruction Set Computer CPU) development, evolving its architecture from V3 to V7. As ARM has always sold intellectual property (IP) to major semiconductor manufacturers without engaging in chip production and sales itself, and due to the significant advantages of its core designs, such as low power consumption and low cost, it has gained strong support from numerous semiconductor manufacturers and original equipment manufacturers (OEMs). ARM has achieved tremendous success in the 32-bit embedded application field, capturing over 75% of the market for 32-bit RISC embedded products, establishing a market leadership position in low-power, low-cost embedded applications. More than 50 international companies design

Understanding ARM Architecture and Processors

2. ARM Architecture and ProcessorsARM does not manufacture silicon devices. Instead, ARM creates microprocessor designs that are licensed to semiconductor companies and original equipment manufacturers (OEMs), who integrate them into system-on-chip (SoC) devices.To ensure compatibility between different implementations, ARM defines architectural specifications that dictate how compliant products should behave. Processors implementing the ARM architecture must conform to specific versions of the architecture.The ARM architecture supports implementations across a very wide range of performance points. Its simplicity allows for very small implementations, enabling very low power consumption.The Cortex-A series processors covered in this book conform to the ARMv7-A architecture. There may also be multiple processors with different internal implementations and microarchitectures that have different cycle times and clock frequencies but conform

Understanding the Complex Relationships Between MCU, ARM, DSP, and FPGA in Embedded Systems

Follow UsLearn Embedded Systems Together, let's learn and grow togetherFirst of all, "embedded" is a concept, and there is no accurate definition; each book has its own definition. However, the main idea is the same: compared to general-purpose systems like PCs, embedded systems are specialized systems with a streamlined structure, retaining only the necessary parts in hardware and software while eliminating the unnecessary ones. Therefore, embedded systems generally have characteristics such as portability, low power consumption, and single performance.Then, MCU, DSP, and FPGA all belong to the category of embedded systems and are tools used to achieve specific purposes.MCU, commonly known as "microcontroller", has evolved over the years and is no longer just the Princeton structure 51; its performance has

Exciting Progress on iOS 15.x arm64 Jailbreak: Successful Plugin Installation

First, let's look at the key points, then the original textThe key point: There has been progress in jailbreaking iOS 15.x on mobile devices A9 - A11. The expert Wh1te4ever successfully installed plugins using an iPhone 6S on iOS 15.1 KFD, which allows for mobile jailbreaks to use passcodes without relying on a computer.Regarding the progress of the iOS 15.x arm64 jailbreak, specifically for iPhone 6S - X devices, it is well-known that the iOS 15.x jailbreak can only be used with a computer boot. Especially for iPhone X devices, once jailbroken, it will prevent the use of the lock screen passcode, which is particularly frustrating.For the Dopamine iOS 15.0 - 15.4.1 jailbreak, this tool currently supports A12 - A15

What Wonders Will ARM in FPGA’s Clothing Perform? – Zynq

What Wonders Will ARM in FPGA's Clothing Perform? - ZynqThe term Zynq easily brings to mind zinc, the most common chemical element found in batteries, solar screens, alloys, and pharmaceuticals. Zinc can enhance functionality when alloyed with other metals, displaying various colors depending on the alloy's composition. The most common use of zinc is electroplating. So, what is the connection between this name and electroplating? In April 2010, at the Embedded Systems Conference in Silicon Valley, Xilinx released the architecture details of its extensible processing platform, a SoC based on the ubiquitous ARM processor designed to meet the high performance, low power, and multi-core processing requirements of complex embedded systems. The core essence of the Xilinx extensible processing platform chip
