What is the difference between linux and ucos

Difference: 1. ucos is a real-time operating system based on ROM, while Linux is a multi-user operating system based on POSIX and UNIX; 2. ucos has high execution efficiency, small footprint, real-time and Linux has the characteristics of strong scalability, stability, powerful network functions and excellent file system.

μC/OS II (Micro-Controller Operating System Two) is a ROM-based, scalable, preemptive, real-time multitasking kernel that is highly portable and particularly suitable for microprocessors. and controller, suitable for real-time operating systems (RTOS) with comparable performance to many commercial operating systems.

Linux is a free-to-use and freely disseminated Unix-like operating system. It is a multi-user, multi-task, multi-thread and multi-CPU operating system based on POSIX and UNIX. It can run major UNIX software tools, applications and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the network-centric design philosophy of Unix and is a multi-user network operating system with stable performance.

The difference between linux and ucos

ucos has the characteristics of high execution efficiency, small footprint, strong real-time and scalability, etc. Linux has stability and strong network features and a great file system.

The connection between linux and ucos

They are two free embedded operating systems with excellent performance and open source code and are widely used. They can be used as research real-time operating systems and An example of a non-real-time operating system.

Extended knowledge

μC/OS II can be simply regarded as a multi-task scheduler. On top of this task scheduler, multi-task operations are improved and added. System-related system services, such as semaphores, mailboxes, etc. Its main features are open source code, clear and clear code structure, detailed comments, organized, good portability, cuttable, and solidifiable.

The kernel is preemptive and can manage up to 60 tasks. Since 1992, μC/OS II has been used in a wide range of applications from cameras to avionics due to its high reliability, robustness and safety.

The Linux operating system was born on October 5, 1991 (this is the first time the date was officially announced to the outside world). There are many different Linux versions of Linux, but they all use the Linux kernel. Linux can be installed on a variety of computer hardware devices, such as cell phones, tablets, routers, video game consoles, desktop computers, mainframes, and supercomputers.
