Abstract The Neural Processing Unit (NPU) adopts a “data-driven parallel computing” architecture, particularly adept at processing large-scale multimedia data such as video and images. This article analyzes the working principles of NPUs in modern smart devices, architectural features, differences from CPUs/GPUs, and application scenarios, providing a detailed explanation of NPUs and their distinctions from CPUs … Read more
In the wave of smart grid construction, power meters have evolved from traditional measurement tools to data nodes that integrate real-time monitoring, fault diagnosis, and energy management. Their hardware architecture must meet three stringent requirements: millisecond-level data acquisition (for example, harmonic analysis requires sampling tens of thousands of times per second), extreme environmental tolerance (from … Read more
In embedded development, there is a crucial yet often overlooked “invisible tool”—the JTAG interface. It is embedded within chips, supporting core operations such as debugging and programming, and developers typically interact with it through IDEs without delving into the underlying details. However, as devices trend towards miniaturization and high integration, the pin and wiring requirements … Read more
