I have previously recommended the RK3399, but it was relatively expensive. This time, I would like to recommend a version that costs only 50 Yuan, which is one-third cheaper than before. The key features are 4GB RAM and 32GB storage, providing higher specifications and better playability. RK3399 Specifications Details Six cores and six threads, dual … Read more
(Source: semiwiki)Data centers are typically seen as a battleground between CPUs (x86, ARM, RISC-V) and GPUs (NVIDIA, AMD, custom ASICs). However, behind this prominent competition, a quiet revolution is taking place: ARM is quietly replacing Intel and AMD in the data processing unit (DPU) market.The DPU (also known as SmartNIC) is responsible for the “pipeline” … Read more
Scan to FollowLearn Embedded Together, let’s learn and grow together We know that STM32 microcontrollers are an organic combination of ST’s peripherals and various Cortex cores from ARM.ST has produced many microcontrollers based on different Cortex-M cores. I found a comparison table of different Cortex-M core characteristics on the ARM website, and I would like … Read more
AI is empowering mobile phones to become personal intelligent terminals, driving growth in the mobile phone market. In the previous article, we detailed how NPUs provide energy efficiency far exceeding that of CPUs/GPUs through three major designs: fixed computation flow, tightly coupled memory, and mixed low-precision inference, making it a core upgrade direction for mobile … Read more

Recently, I discovered a phenomenon: in the AUTOSAR OS, if an interrupt occurs after task scheduling, the BASEPRI is used to control the enabling and disabling of interrupts. If it occurs before task scheduling, PRIMASK is used for control. This article introduces the differences between these two. 1. Differences <span>PRIMASK</span>: All or nothing switch. It … Read more
