ver0.3 Introduction Those who have persisted in reading this article are already remarkable, as they now understand the weak memory ordering architecture of ARM. You not only understand the types of memory, the memory sharing mechanisms, and the memory consistency mechanisms, but also the CPU architecture and the microarchitecture of processors, all of which lay … Read more
BlueField The DPU is developed based on SmartNIC technology after NVIDIA acquired the Israeli network chip company Mellanox. The latest version is theBlueField-3 DPU, which began full production in 2023.The next generationBlueField-4 is expected to be released in 2025. Compared to theBlueField-3 DPU, the AI acceleration will use an ARM processor, while theBlueField-4 DPU will … Read more
Recently, ARM launched the Cortex-A77 CPU core and the Mali-G77 GPU core. As we know, ARM cores have always been the foundation of mobile platforms for Huawei, Samsung, and Qualcomm. Although both Samsung and Qualcomm are actively developing their own CPUs or GPUs, they still rely on ARM. It is foreseeable that these two cores … Read more
[Continuing from Last Time] Last time we discussed: Arm-2D is a GUI toolkit for microcontrollers with limited resources, and we systematically introduced how to deploy the Arm-2D library in an MDK project, further explaining how to use the PFB Helper to achieve “infinitely variable speed” between “frame rate and RAM usage”. Today, we will continue … Read more
In today’s DIY computer market, overclocking is no longer a forbidden zone for ordinary players. However, we must accept the reality: graphics cards are essentially maxed out, and processors can easily reach 5GHz+ with automatic turbo boost. Overclocking memory, especially DDR5 memory, has also become a field that ordinary DIY players can experiment with. As … Read more
On March 28, 2025, global semiconductor giant Texas Instruments (TI) announced layoffs at its Lehi, Utah facility, involving adjustments to certain positions. This announcement comes as the company receives $1.61 billion in funding support from the U.S. CHIPS and Science Act, accelerating the expansion of its second 300mm wafer fab (LFAB2) in Utah, sparking widespread … Read more
1. Layoff Incident: Dual Signals of Capacity Optimization and Strategic Contraction 1.1 Scale of Layoffs and Details Disclosed In March 2025, a statement released by Texas Instruments (TI) sent ripples through the semiconductor industry, announcing a layoff plan at its Lehi, Utah plant. This decision was not without warning; looking back, TI has been gradually … Read more
Texas Instruments CEO Haviv Ilan made a statement during the earnings call that stirred the undercurrents of the global semiconductor supply chain. “If the Americans really ramp up the tariffs, our Chengdu factory is not to be underestimated!” said the Israeli executive, who leads the world’s largest analog chip company, while tapping his finger on … Read more
On April 11, the China Semiconductor Industry Association issued an urgent notice regarding the identification rules for the “country of origin” of semiconductor products. Today, I would like to share my personal views based on some interpretations available online. This matter is quite simple. Semiconductor chips are subject to tariffs based on their country of … Read more
The new policy issued by the China Semiconductor Industry Association on April 11, 2025, shifts the integrated circuit origin certification standard from “packaging location” to “wafer fabrication location.” This change will accelerate the migration of global chip companies’ wafer fabrication processes to mainland China. As a critical validation step between chip R&D and mass production, … Read more
