This article introduces the relevant knowledge of "Why choose C language as an embedded development language". In the operation of actual cases, many people will encounter such a dilemma. Next, let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Friends who know embedded development know very well that the core development language is C language, and C language occupies a very important position in the process of embedded development. This should be inevitable, embedded development is developed within the operating system, and all the kernels of the operating system are written in C language, so it must have certain advantages to choose C language in the process of embedded development.

So what are the characteristics of C language?

1. C language has excellent portability and can run on a variety of software / hardware platforms with different architectures.

2. C language has a compact and flexible syntax mechanism, and can directly access the hardware.

3. C language has high running efficiency.

What does embedded software development need to rely on?

The main considerations are three aspects: performance, security, and development efficiency (including code portability, etc.). In terms of performance, that is, running efficiency, assembly is obviously the highest, but assembly is obviously the lowest in terms of security and development efficiency. so unless it is an extremely high-performance embedded development platform or the system is too simple to support high-level languages, not many people use assembly language. Generally speaking, assembly language is used in initialization.

For other high-level languages, the running efficiency is generally low, and the running efficiency of C language programs can reach 80% of that of assembly, while other development programs may only be 80% of C language, and the source code and object code may also be relatively long. in this way, it will take up a lot of memory. The programming of embedded development needs to run on the development board, and if it takes up too much memory, it will affect the corresponding performance, so the advantage of C language will be highlighted.

These are the reasons why C language is chosen as the embedded development language, but C language also has its own limitations. In the process of using C language for development, we must try our best to avoid and overcome these shortcomings, to improve the quality of the corresponding code, so that the written program will be better, embedded development will become more and more perfect.

This is the end of the content of "Why choose C language as an embedded development language". Thank you for your reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
