VxWorks is a real-time operating system (RTOS) developed as proprietary software by Wind River of Alameda, California, US. First released in 1987, VxWorks is designed for use in embedded systems requiring real-time, deterministic performance and, in many cases, safety and security certification, for industries, such as aerospace and defense, medical devices, industrial equipment, robotics, energy, transportation, network infrastructure, automotive, and consumer electronics.〔"(VxWorks ) Goes 64-bit", Electronic Design, March 25, 2011〕 VxWorks supports Intel (x86, including the new Intel Quark SoC,〔Intel Tackles SoC With (Quark )"' EE Times, October 7, 2013〕 and x86-64), MIPS, PowerPC, SH-4, and ARM architectures.〔Wind River Expands (Hardware Support ) for VxWorks, Bloomberg News at bloomberg.com, March 24, 2010〕 The RTOS can be used in multicore asymmetric multiprocessing (AMP), symmetric multiprocessing (SMP), and mixed modes〔(RTOS ) Handles AMP and SMP, electronic design, March 2009〕 and multi-OS (via Type 1 hypervisor)〔(【引用サイトリンク】title=Intel Adds Virtualization Platform for Industrial Systems )〕 designs on 32- and 64-bit processors.〔(Embedded Star ) Article, February 2011〕 VxWorks comes with the kernel, middleware, board support packages, Wind River Workbench development suite and complementary third-party software and hardware technologies. In its latest release, VxWorks 7, the RTOS has been re-engineered for modularity and upgradeability so the OS kernel is separate from middleware, applications and other packages.〔(Wind River ) reinvents real-time system for the Internet of Things, iTERS news, March 2014〕 Scalability, security, safety, connectivity, and graphics have been improved to address Internet of Things (IoT) needs.〔Wind River (Reinvents ) the RTOS for the IoT, Business Wire, February 2014〕 ==History== VxWorks started in the late 1980s as a set of enhancements to a simple RTOS called VRTX sold by Ready Systems (becoming a Mentor Graphics product in 1995). Wind River acquired rights to distribute VRTX and significantly enhanced it by adding, among other things, a file system and an integrated development environment. In 1987, anticipating the termination of its reseller contract by Ready Systems, Wind River developed its own kernel to replace VRTX within VxWorks.〔(Lord of the Toasters ), Wired (magazine) interview with Jerry Fiddler, September 1998〕 VxWorks key milestones are:〔 (Company Histories ), Funding Universe〕 * 1980s: (32-bit processing) – VxWorks adds support for 32-bit processors * 1990s: (the Internet) – VxWorks 5 becomes the first RTOS with a networking stack * 2000s: (multi-core) – VxWorks 6 supports SMP and adds derivative industry-specific platforms * 2010s: (64-bit processing and the Internet of Things) – VxWorks adds support for 64-bit processing〔 and introduces VxWorks 7 for IoT.〔Wind River (Outfits VxWorks ) for the Internet of Things, Computer World〕 VxWorks is owned by Intel. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「VxWorks」の詳細全文を読む スポンサード リンク
