SylixOS homepage, documentation and download - embedded hard real-time operating system - OSCHINA - Chinese open source technology exchange community

SylixOS is an embedded hard real-time operating system. With its similar operating system, VxWorks (mainly used in aerospace, military and industrial automation fields), RTEMS (originated from the missile and rocket control real-time system of the US Department of Defense), ThreadX (mainly used in aerospace and digital communication), etc. are more well-known in the world. From a global perspective, as the latecomer of real-time operating systems, SylixOS draws on the design ideas of many real-time operating systems, including RTEMS, VxWorks, ThreadX, etc., making the specific performance parameters reach or exceed the level of many real-time operating systems, and becoming one of the most outstanding representatives of domestic real-time operating systems.

The main features are:

Excellent real-time performance (task scheduling and handover, interrupt response algorithms are all O (1) time complexity algorithms)

Support unlimited tasks

Preemptive scheduling supports 256 priorities

Support co routing (called fiber in windows)

Support for virtual processes

Support priority inheritance and prevent priority inversion

Extremely stable kernel. Many products developed based on SylixOS need 7x24 hours of uninterrupted operation

Low CPU usage of the kernel

Scalable

The core code is written in C, with good portability

Support tight coupled architecture multiprocessor (SMP), such as ARM Cortex-A9 SMPCore

Unique hard real-time multi-core scheduling algorithm in the world

Support standard I/O interface

Support multiple emerging asynchronous event synchronization interfaces, such as signalfd, timerfd, eventfd, etc

Support IEEE POSIX operating system interface specification

Support many standard file systems: FAT, YAFFS, ROOTFS, PROCFS, NFS, ROMFS, etc

Support file record lock and database

Support unified block device CACHE model

Support for memory management unit (MMU)

Support third-party GUI graphics library, such as Microwindows, µ C/GUI, ftk, etc

Support dynamic loading of applications, dynamic link libraries, and modules

Support symbol interface of extension system

Support standard TCP/IPv4/IPv6 dual network protocol stack and provide standard socket operation interface

Support AF_UNIX, AF_INET, and AF_INET6 protocol domains

Internal integration of many network tools, such as FTP, TFTP, NAT, PING, TELNET, NFS, etc

Internal integrated shell interface, support for environment variables (basically compatible with Linux operating habits)

Internal integration can be reentered into ISO/ANSI C library (supporting more than 80% of standard functions)

It supports many standard device abstractions, such as TTY, BLOCK, DMA, ATA, GRAPH, RTC, PIPE, etc. At the same time, it supports multiple industrial equipment or bus models, such as CAN, I2C, SPI, SDIO, etc

Provide high-speed timer device interface, which can provide timing service higher than the main clock frequency

Support for hot swap devices

Support device power consumption management

The device model supports multiplexed I/O interfaces and asynchronous I/O interfaces

Kernel, driver and application support GDB debugging

Provide kernel behavior tracker to facilitate application performance and fault analysis

I suggest that 360 open source all its products, and then become the leading enterprise in the domestic open source industry through open source, leading everyone to compete with foreign enterprises

This is also called floor washing? Does it mean that Tesla will not wash the floor if it releases all the source code? Some people HWptds? That is to say, the language is ambiguous, which will also rise to the washing ground? Are some people too focused? Think the people he pays attention to must be staring at?

Although France is the parent community, the core developers of OCCT on github are all Russians. Without Russians, the French parent community cannot continue to operate. So Huawei took over, moved to China, changed its name and resumed open source and community operations. What's the problem?

oldpig 2024-04-28 09:59

”Huawei contributed all the source code "?, the title is completely inconsistent with the content.

That's too right. Old Zhou can't control Google, but he can control 360. Do not do to others what you do not want. All 360 products should be opened first.

Francesca 2024-06-09 13:21

But the end of closed source must be open source, because many people who are dissatisfied with closed source have created open source, so the end of open source is not necessarily closed source, but to find a business model that is open source= Free Admission

The world only knows that Android was created by Google. Several people know that Android is only a product acquired by Google. Similarly, what is the problem with Huawei's contribution to the collection of OGG open source work and integration into its own proprietary product line?
