Question:An embedded real-time operating system uses a certain scheduling algorithm. When a task is nearing its deadline, the scheduling algorithm adjusts the priority of that task to the highest in the system, allowing it to acquire CPU resources for execution. What type of scheduling algorithm is this?. A: Priority Scheduling Algorithm B: Preemptive Priority Scheduling … Read more

Word Count: 6000 Practical Index: ⭐⭐⭐⭐⭐ This question is asked very frequently, and I personally agree with the following answer: “Microcontrollers are now classified under embedded systems, but embedded systems have clear definitions. A system with a computer architecture is called an embedded system. A microcontroller is simply the CPU part of an embedded system. … Read more
A few days ago, I saw a message from Jean Labrosse on LinkedIn. He informed his friends that he retired on February 28 and will continue to engage in activities related to embedded software, such as giving talks and writing articles. He also mentioned that Silicon Labs has announced the open-sourcing of the Micrium µC/OS … Read more

What is a framework? A program framework is similar to a file outline or template. Writing a program is like writing an article; without an outline or template, it can be quite cumbersome. Why Have a Framework? To save time and reduce errors. For a specific type of program, the logical structure of the code … Read more
1. Concept and Classification of Memory In computing systems, memory is used to store variables and intermediate data. The system memory can be divided into two types: Internal Storage Space (RAM): Typically refers to Random Access Memory, which allows fast data access and random access, but data is lost when power is off. External Storage … Read more
