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

Let’s illustrate this issue with a concrete example. How does a typical task system handle information in embedded systems? The process looks like this: • Retrieve new data • Filter/Process data • Output data Pretty straightforward, right? We know that for real-time embedded system design, the main goal is determinism and minimizing jitter. The three … Read more
The Loongson ecosystem is becoming increasingly complete, following the successful deployment of SylixOS domestic real-time operating system on the RK3568 development board[details], the domesticLoongson 2K100 development platform can nowsmoothly run the SylixOS domestic real-time operating system. SylixOS is designed with apreemptive, multi-tasking, hard real-time approach for the entire operating system. It has been widely applied … Read more
1. The Birth of uC/OS-II: From Open Source Experiment to Industry Benchmark Background and Origin uC/OS-II (Micro-Controller Operating System Version II) was born in 1992, developed by embedded systems pioneer Jean J. Labrosse. Its predecessor, uC/OS (1991), was initially released as a teaching tool in the magazine “Embedded Systems Programming,” and later evolved into a … Read more
Last night, a student studying abroad asked me about embedded systems. At first, I thought it was a technical exchange, but then he sent me a copy of past exam questions 😂. Upon reviewing, it mainly covered some basic theoretical analyses of real-time systems and some understanding of multitasking code. The main focus was on … Read more
