Bradley then remarked, “If we expand the war into Communist … Read more
In 2010, the Berkeley research team aimed to design a CPU. However, Intel’s licensing for x86 was very strict, ARM’s instruction set licensing was expensive, and MIPS, SPARC, and Open Power also required their respective company licenses. With limited options, the Berkeley research team decided to start from scratch to design a new instruction set. … Read more

I am Lao Wen, an embedded engineer who loves learning. Follow me to become better together! An architectural pattern is a general reusable solution to a commonly occurring problem within a given context in software architecture. A pattern is a solution to a problem in a specific context. However, many developers still struggle to understand … Read more
Embedded software development is a widely used and continuously evolving technology field. To meet the needs of different application scenarios, developers can adopt various architectural approaches. In this article, we will explore three common architectures in embedded software development: Front and Back Sequential Execution Method, Time-Slicing Method, and Operating System. 01. Front and Back Sequential … Read more

Abstract: For microcontroller programs, everyone is familiar, but very few actually consider the architecture. With the increasing number of program developments, having an architecture is very necessary. There are roughly three types of application architectures: 1. Simple front and back sequential execution programs, this method is used by most people, without needing to think about … Read more
Embedded software may experience coupling between drivers and applications due to hardware resource limitations. However, for large projects with ample resources, complex business logic and the need for future expansion and maintenance necessitate the adoption of layered and modular thinking, which is the essence of architectural patterns. Common architectural patterns available in the market include … Read more
