The REX Operating System (Real-time Executive Operating System) is a real-time operating system (RTOS) developed by Qualcomm for the ARM processor based mobile phone Dual-Mode Subscriber Station (DMSS) or Advanced Mode Subscriber Software (AMSS) development. As of 2007, most Korean cell phones ran on REX. REX is a combination of two operating systems: L4A Pistachio embedded microkernel and Iguana, with extensive modifications and extensions by Qualcomm and HTC.

dbo:abstract
  • The REX Operating System (Real-time Executive Operating System) is a real-time operating system (RTOS) developed by Qualcomm for the ARM processor based mobile phone Dual-Mode Subscriber Station (DMSS) or Advanced Mode Subscriber Software (AMSS) development. As of 2007, most Korean cell phones ran on REX. REX is a combination of two operating systems: L4A Pistachio embedded microkernel and Iguana, with extensive modifications and extensions by Qualcomm and HTC. Originally developed for the Intel 80186, it was then ported to ARM, and x86 architectures are no longer supported. REX is not POSIX compliant or open-source software and requires a proprietary software license from Qualcomm for use. It seems not to be actively developed or marketed as of 2012, but is used in currently or recently sold low end cell phones, typically for use by pay-as-you-go customers, like the Samsung SPH-M300.

  • REX OS (Real-Time Executive Operating System、レックス オーエス)とは、クアルコム（Qualcomm）がかつて採用していた、携帯電話用ベースバンド・チップソフトを動かす為のARMベースのリアルタイムオペレーティングシステム。古くは、cdmaOne用、並びにCDMA2000用チップセットだけであったが、サポートするエアインタフェースの拡大に伴い、W-CDMA、GSM用のチップセットでも使われている。ライセンスは、クローズドなソースライセンスなので、クアルコムから開発ライセンスを取得しないとソースを見ることが出来ない。 (ja)
