As a core component of embedded systems, the presence of the ARM processor ensures the stability and performance of the system. To better ensure the normal operation of embedded systems, the ARM processor provides seven operating modes, each with its specific application scenarios and privilege levels. 1. User Mode (USR) Normal program execution mode. Cannot … Read more
Low-power design is an important aspect of chip design, crucial for extending the battery life of portable devices, reducing energy consumption, and improving overall system performance. Here are some common low-power design methods: 1. Clock-Based Low-Power Design This method involves shutting down or reducing the clock frequency when not needed, as clock activity is the … Read more
The demand for device driver models includes the bus, device, and driver models. If we compare their relationships to examples in everyday life, it becomes easier to understand. For instance, a charging wall socket quietly embedded in the wall can fulfill its mission of charging, regardless of whether the device is a computer or a … Read more
“ The Industrial Internet of Things (IIOT) is the application of the Internet of Things in the industrial sector, but it is not simply equivalent to ‘Industry + IoT.’ The complex industrial scenarios make its connotation richer!” 01 — Concept Positioning:The Industrial Internet of Things is a set of enabling technology systems that support smart … Read more
