IntervalZero, Inc. develops hard real-time software and its symmetric multiprocessing (SMP) enabled RTX and RTX64 software transform the Microsoft Windows general-purpose operating system (GPOS) into a real-time operating system (RTOS). IntervalZero and its engineering group regularly release new software (cf its history).〔(Recognizing excellence among Windows Embedded partners )〕 Its most recent product, RTX64, focuses on 64-bit and symmetric multiprocessing (SMP) to replace dedicated hardware based systems such as digital signal processors (DSPs) or field-programmable gate arrays (FPGAs) with multicore PCs.〔(IntervalZero RTX Software Outperforms Digital Signal Processors )〕 For instance, an audio mixing surface manufacturer which largely deployed DSP based systems, switched to personal computer (PC) based systems, dedicating multi-core processors for the real time audio processing. Founded in July 2008 by a group of former Ardence executives, IntervalZero is headed by CEO Jeffrey D. Hibbard. The firm has offices in Waltham, MA; Nice, France; Munich, Germany, and Taiwan, ROC. This global presence is important because these solutions are deployed worldwide, primarily in industrial automation, military, aerospace, medical devices, digital media, and test and simulation software. The corporate name, IntervalZero, comes from the firm's mission to deliver deterministic, hard real-time functionality. An "interval of zero" is the technical definition of the optimal experience between a system command and execution. ==History== IntervalZero's lineage traces back to 1980, when a group of Massachusetts Institute of Technology (MIT) engineers started VenturCom and began to develop expertise in embedded technology. It was during this time that Venix was developed and marketed. Their first innovation was to focus on Windows NT 4.0 as a possible real-time solution for the Industry in 1995 by releasing RTX.〔(Realtime Windows NT )〕 Since then, a lot of controllers are PC and Windows based. Their second innovation came as a second product, Component Integrator, which makes Windows NT 4.0 an embedded OS. It was licensed by Microsoft a few years later and became the origin of Windows NT Embedded.〔(Microsoft Licenses VenturCom’s Component Integrator Technology )〕 In 2004, VenturCom, was renamed Ardence. On 20 December 2006, Citrix Systems announced an agreement to acquire Ardence's enterprise and embedded software businesses and integrated the software streaming products into the Citrix portfolio in 2007 and early 2008.〔(Citrix acquires Ardence for PC, Server Provisioning - Network World )〕 In early 2008, Citrix agreed to sell the embedded business to IntervalZero and Citrix has retained a minority ownership the firm. On 28 July 2008, IntervalZero announced that it acquired the Ardence embedded software business from Citrix Systems Inc.〔(Citrix Sells its Ardence Embedded Software Business to IntervalZero - TMCNet )〕 IntervalZero officially completed the acquisition on July 15, 2008. 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「IntervalZero」の詳細全文を読む スポンサード リンク
