1IntroductionImagine if the MCU we work with only runs bare-metal programs; when it reaches a thread that includes a delay, our CPU would start to “idle”.To maximize CPU utilization, we need to use an RTOS (Real-Time Operating System). In simple terms, an RTOS is an operating system that schedules all available resources to complete real-time … Read more
Hello everyone, I am Xuanyuan. In this article, we will review embedded systems and architecture diagrams.. An Embedded System is a computer system specifically designed for a particular application, and its architecture has developed alongside the gradual application of embedded systems. The design of embedded software architecture is closely related to the architecture of embedded … Read more
Potential Issues in Embedded Development 1 Concurrency Issues The efficiency of concurrent program execution is low when writing bare-metal software. Inevitably, there will be a massive while(1) loop in the main program, which contains almost all the business logic of the project. Since each business logic contains delay functions that cause loop waiting, this leads … Read more
What is a Real-Time Operating System (RTOS) A Real-Time Operating System (RTOS) is an operating system specifically designed for real-time applications. Real-time applications require predictable responses within specific time constraints, so RTOS focuses on providing an emphasis on timing constraints to ensure that the system can meet real-time performance requirements. 1. Real-Time Performance: Hard Real-Time … Read more
