Intel and Arm Diversify Their Focus at Computex 2018

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

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

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

Understanding ARM Architecture and Processors

2. ARM Architecture and Processors

ARM 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

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

First 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
