Friends involved in IC design and verification know that simple single-core MCU code is everywhere. However, if you want to advance and study Multi-core Boot, Bus Arbitration, Cache Coherence, or Deadlock Detection, having a reliable multi-core RTL source code is essential. Without it, even the most skilled craftsman cannot cook without rice. At the end … Read more
Understanding the Core Differences Between x86, x64, and ARM: Implications for Software Compatibility Introduction Architecture Designx86, x64, and ARM are three major processor architectures, and their core differences lie in the instruction sets and data processing capabilities. x86 is a traditional 32-bit architecture represented by Intel and AMD processors, excelling in multitasking and complex computations. … Read more
1. What is EtherCAT? A Clever Analogy First, forget the traditional network concept. You can imagine it like this:Traditional Ethernet (like TCP/IP): It’s like a postman delivering letters to every household in an apartment building. The postman has to walk to each door (node), knock, wait, and hand over the letter (data) to the resident. … Read more
Expansion of the Chip Alliance NVIDIA is building an unprecedented AI computing empire, and its approach is not entirely closed off. The latest major news is that Arm has announced its entry into the NVLink Fusion ecosystem. This is not just about adding a partner; it opens a direct gateway to NVIDIA’s GPU core for … Read more
It is well known that RISC-V processor IPs are significantly cheaper than ARM. If your management asks you to consider domestic IP alternatives or budget reductions, the domestic RISC-V IP is undoubtedly the first choice. When comparing performance, should ARM’s NEON be compared to RISC-V’s P extension or V extension? First, let’s introduce RISC-V’s P … Read more
Arm and NVIDIA Make Big Moves! A Paradigm Shift in CPU-GPU Interconnects “Five years ago, there was an acquisition attempt, and five years later, a partnership!” On November 17, the chip industry was shaken by a significant collaboration — Arm announced that its CPUs can seamlessly integrate with AI chips through NVIDIA’s NVLink Fusion technology. … Read more

On September 30, 2025, the Delaware court in the United States issued a first-instance judgment in the licensing dispute case between ARM and Qualcomm. 1. Background: Licensing, Acquisition, and Litigation In 2021, Qualcomm announced its acquisition … Read more
I remember seeing a Chinese company at a conference in Europe, where they arranged a lion dance. However, the leader from that country was very dissatisfied and said on the spot that such things should not be brought over; we should learn from the foreigners and not bring domestic elements… As a result, today ARM … Read more
Recently, a province has dramatically changed its “Two Chips and One Ecosystem” system based on domestically produced ARM chips. According to industry news, in order to broaden the computing ecosystem and decouple the underlying technology route, the previous “Two Chips” consisting of Feiteng and Kunpeng will remove their brand attributes and expand to a broader … Read more
The choice of computer architecture directly affects product performance, power consumption, and cost. This article focuses on the three mainstream architectures: ARM, x86, and RISC-V, comparing them from three dimensions: technical characteristics, application scenarios, and ecosystem maturity, providing developers with precise selection criteria. 1. ARM Architecture: The King of Mobile and Embedded Fields Core Advantages … Read more
