When I first introduced cloud phones (Unveiling Cloud Phone Technology! Achieving Low-Cost Transformation of One Computer into Hundreds of “Virtual Phones” in Practice), I mentioned that the mobile box from Magic Cloud was a bit expensive. However, running it on a server lacked graphical acceleration, which slightly affected the experience, so I tried running it … Read more
Arm has recently disclosed its product brand restructuring strategy, planning to provide self-developed chips to customers, while also mentioning its reliance on the Chinese market and the competitive risks posed by RISC-V.ARM has suddenly announced the abandonment of the Cortex brand, which it has used for twenty years. This once-arrogant British chip giant may indeed … Read more

In embedded systems,the core of a microcontroller (MCU) — the core (Core) determines the performance boundaries, power consumption characteristics, and software ecosystem of the entire platform. The current mainstream microcontroller architectures are represented by ARM and RISC-V, one being the cornerstone of the mature industrial sector, and the other being the pioneer of the open-source … Read more
Why Are Compilers So Critical? On resource-constrained embedded platforms, compilers are not only responsible for translating source code into machine instructions but also undertake multi-level optimization tasks: Code Optimization and Size Reduction: Through function inlining, loop unrolling, constant propagation, and link-time optimization (LTO), firmware performance is enhanced and size is minimized. Hardware-Related Parameter Configuration: By … Read more
Recently, I discovered an interesting development board. This development board integrates ARM cores, NPU cores, and even FPGA cores. It is the newly released YM90X development board from Mill. It is based on the chip developed by Anlu Technology. Shanghai Anlu Information Technology was listed on the Shanghai Stock Exchange’s Science and Technology Innovation Board … Read more
First, the term “embedded” is a concept that lacks a precise definition, with various books offering their own interpretations. However, the main idea is similar: compared to general-purpose systems like PCs, embedded systems are specialized systems with a streamlined structure, retaining only the necessary components in both hardware and software while discarding the unnecessary parts. … Read more
“ This is definitely a legendary figure. ”In recent months, rumors have increased regarding Apple’s plan to fully transition the Mac platform to ARM chips as early as 2020. Today, there are reports that the company has taken a significant step forward in achieving this goal. According to reports, ARM’s Chief System Architect Mike Filippo … Read more
