What is the difference between Vxworks and Linux systems?

1.VxWorks is a real-time operating system launched by the American Wind River System Company (hereinafter referred to as Wind River Company, WRS Company). Tornado is a real-time operating system development environment launched by WRS Company. It is similar to Microsoft Visual C, but provides a richer debugging and simulation environment and tools.

The main application areas of the embedded Vxworks system are as follows: 1. Data network: such as: Ethernet switches, routers, remote access servers, etc. 2. Remote communication: such as: dedicated for telecommunications Packet switches and automatic call distributors, cellular phone systems, etc. 3. Medical equipment: such as: radiotherapy equipment 4. Consumer electronics: such as: personal digital assistants, etc. 5. Transportation: such as: navigation systems, high-speed train control systems, etc. 6. Industry: such as: robots 7. Aerospace: such as: satellite tracking system 8. Multimedia: such as: video conferencing equipment 9. Computer peripherals: such as: X terminal, I/O system, etc. In short, the system structure of VxWorks is quite small The hierarchical structure of the microkernel. The kernel only provides multitasking environment, inter-process communication and synchronization functions. These functional modules are sufficient to support the rich performance requirements provided by VxWorks at a higher level.

2.Linux is the collective name for a class of Unix computer operating systems. The name of the kernel of the Linux operating system is also "Linux". The Linux operating system is also the most famous example of the development of free software and open source. Strictly speaking, the word Linux itself only refers to the Linux kernel, but in fact people are accustomed to using Linux to describe the entire operating system based on the Linux kernel and using various tools and databases of the GNU Project. Linux is named after computer amateur Linus Torvalds.

Applications of Linux

In the past, Linux was mainly used as a server operating system because of its cheapness, flexibility and Unix background. Traditionally, the Linux-based "LAMP (combination of Linux, Apache, MySQL, Perl/PHP/Python)" technology has been widely popular among the developer community. It is also the most commonly used by current website service providers. platform. Based on its low cost and high degree of configurability, Linux is often used in embedded systems, such as set-top boxes, mobile phones, and mobile devices. On mobile phones, Linux has become the main competitor of Symbian OS; on mobile devices, it has become another option besides Windows CE and Palm OS. The currently popular TiVo digital cameras use customized Linux. In addition, there are many hardware-based network firewalls and routers, such as some LinkSys products, which are driven internally by Linux and use the firewall and routing functions provided by the operating system. More and more supercomputers use Linux. According to the TOP500 supercomputer list in November 2008, the fastest supercomputers in the world currently use Linux as their operating system. Among the 500 systems listed in the table, 439 systems (or 87.8%) use Linux as the operating system. The SONY PlayStation 3, which was launched in 2006, can also use the Linux operating system, and it has Yellow Dog Linux that can make it a desktop system. Previously, Sony had also launched a set of DIY components called PS2 Linux for their PlayStation 2. Ubuntu has restored PPC support (including PlayStation 3) since version 9.04. With the promotion of low-priced computers such as OLPC's XO-1 and Asus' Eee PC, many people are optimistic that Linux's market share is growing rapidly in the low-end PC market. But after Windows entered this market, Linux's market share declined rapidly. Now Windows system has an absolute advantage in all PC markets.
