Previously, we introduced I2S. However, we found that I2S has a significant limitation: it can only transmit two channels of audio, left and right. What if I want to transmit 8 channels? 16 channels? Then it becomes impossible! Let’s imagine a scenario. A car of fixed size has two seats, left and right. We arrange … Read more

AbstractThis article provides an in-depth analysis of the core driver implementation mechanism of the Loopback sound card (simple, without involving low-level hardware drivers) from the perspective of character device driver development, based on the Linux kernel 6.8.0 and the QEMU simulation environment with AArch64 architecture. It focuses on the registration management of device nodes and … Read more
Introduction In 2025, within just six months, leading MCU manufacturers such as ST, NXP, and Renesas simultaneously released automotive MCU products equipped with new types of embedded storage (such as PCM and MRAM), breaking the long-standing technical pattern dominated by embedded Flash. While it is still too early to talk about a “standard configuration,” it … Read more
Generative AI has entered the daily work and life of many people. Nowadays, with just a simple input on a computer, users can generate answers or media content to their questions or needs through DNN models (typically using a large language model, LLM). However, the drawback of this application scenario is the overly simplistic operation, … Read more
