Native Paradigms of AI Programming (III): Task Scheduling Strategies Driven by Constraints in Embedded Systems

by

My construction of the concepts of embedded systems and software scheduling began during my doctoral research when I obtained software materials for the Voyager 1 spacecraft through specific channels—this deep-space probe, launched in 1977, is still transmitting data back to Earth. Since 2004, when I led the National 863 Program, high-reliability embedded architecture and scheduling … Read more

Introduction to Python Design Patterns

by

Creational Patterns Singleton Pattern: Ensures that a class has only one instance and provides a global access point to it. Usage Scenarios: Suitable for resource management (such as database connection pools, thread pool management), shared resource access (logging, configuration management), global state management (user session management, cache management), etc. Related Applications: In Java, the <span>java.lang.Runtime</span> … Read more

Friend Functions and Object-Oriented Design: Examining C++ Design Philosophy from the Essence of Encapsulation

by

Abstract One of the core principles of Object-Oriented Programming (OOP) is encapsulation, which binds data and methods that operate on the data into classes, hiding internal implementation details and interacting with the outside only through public interfaces. The friend function in C++ is often criticized for being able to directly access a class’s private and … Read more

C++ Design Patterns: Bridge Pattern

by

The Bridge Pattern is a structural design pattern that separates the abstraction from its implementation, allowing both to vary independently. This pattern introduces a bridge interface that decouples the abstraction layer from the implementation layer, enabling independent extension of both. Core Roles of the Bridge Pattern Abstraction: Defines the abstract interface and contains a reference … Read more

C++ Design Patterns

Introduction In the development process, as the amount of project code increases, the difficulty of maintenance and extension gradually rises. How to design the structure of the code to decouple it, facilitate extension and maintenance, and ease team collaboration is a significant challenge. Design patterns were proposed to address this issue. The design patterns built … Read more

How to Rewrite C++ Programs in C?

Due to the C++ interpreter occupying approximately 500k more storage space than the C language interpreter, it is necessary to rewrite source programs written in C++ into C to save limited storage space, reduce costs, and improve efficiency. The biggest difference between C++ and C is the concept and features of classes in C++. The … Read more

Will Embedded Software and Hardware Engineers Be Replaced by Artificial Intelligence?

For embedded software engineers: For newcomers to the field, writing an I2C driver can take an entire night. They have to meticulously read through the chip manual line by line to understand the register definitions. For instance, when configuring the I2C clock for the STM32, one must first calculate the APB1 prescaler and then set … Read more
