Word Count: 18000 Content Index: ⭐⭐⭐⭐⭐ The Concept of Embedded Systems: Focus on Understanding the Concept of “Embedded” 1. From a hardware perspective, integrating CPU-based peripheral devices into the CPU chip itself. For example, early computers based on the X86 architecture only had arithmetic and accumulator functions. All chips needed to create external bridges for … Read more

Founder and CEO of Horizon Robotics Yu Kai From Center to Edge In the past, big data, big models, and big computing have driven academic research and industrial development. All computing, from PCs to mobile devices, has shown a trend of aggregation towards cloud computing and data centers. However, I believe that in the next … Read more
Embedded operating systems sound quite impressive, but in fact, they are just a streamlined version of an operating system, specially tailored for embedded devices. Today, let’s talk about a particularly interesting embedded operating system – the one based on priority cooperative scheduling. It’s a bit like a well-organized small team, where each member has their … Read more
Introduction From providing chip IP licensing to establishing its own development platform and device management platform mbed, ARM is planning and exploring business model transformation to cope with the changes of the IoT era. Currently, the mbed platform is merely a platform for technical exchange. If ARM’s mbed can become a trading platform for various … Read more

Overview The ring buffer is one of the commonly used data structures in embedded software development, storing content in a first-in-first-out manner, and is used to implement asynchronous “stream” replication of data. Zephyr provides a struct ring_buf abstraction to manage such data structures. Various drivers in Zephyr (UART, Modem, I2S, etc.), as well as shell, … Read more
