WarpOS
WarpOS is a multitasking kernel for the PowerPC (PPC) architecture central processing unit (CPU) developed by Haage & Partner for the Amiga computer platform in the late 1990s and early 2000s. It runs on PowerUP accelerator boards developed by phase5 which contains both a Motorola 68000 series CPU and a PowerPC CPU with shared address space. WarpOS runs alongside the 68k-based AmigaOS, which can use the PowerPC as a coprocessor. Despite its name, it is not an operating system (OS), but a kernel; it supplies a limited set of functions similar to those in AmigaOS for using the PowerPC. When released, its original name was WarpUP, but was changed to reflect its greater feature set, and possibly to avoid comparison with its competitor, PowerUP. It was developed by Sam Jordan using 680x0 and PowerPC assembly language. It was distributed free of charge. History In 1997, Phase5, an Amiga hardware manufacturer, launched their range of PowerPC (PPC) accelerators for the Amiga. Because ...

AmigaOS 4
AmigaOS 4 (abbreviated as OS4 or AOS4) is a line of Amiga operating systems which runs on PowerPC microprocessors. It is mainly based on AmigaOS 3.1 source code developed by Commodore, and partially on version 3.9 developed by Haage & Partner. "The Final Update" (for OS version 4.0) was released on 24 December 2006 (originally released in April 2004) after five years of development by the Belgian company Hyperion Entertainment under license from Amiga, Inc. for AmigaOne registered users.http://www.hyperion-entertainment.biz/8080/news/2007-01-01 History During the five years of development, purchasers of AmigaOne machines could download pre-release versions of AmigaOS 4.0 from Hyperion's repository as long as these were made available. On 20 December 2006, Amiga, Inc. terminated the contract with Hyperion Entertainment to produce or sell AmigaOS 4. Nevertheless, AmigaOS 4.0 was released commercially for Amigas with PowerUP accelerator cards in November 2007 (having been avail ...

Phase5
Phase5 Digital Products is a defunct German computer hardware manufacturer that developed third-party hardware primarily for the Amiga platform. Their most popular products included CPU upgrade boards, SCSI controllers and graphics cards. Notable products Like other third-party Amiga developers, Phase5 developed a range of CPU boards utilizing Motorola 68000 family processors, which powered Amiga systems at the time. Such boards also typically featured onboard RAM controllers with access to faster and greater capacity memory. Notably, Phase5 were unique amongst Amiga developers in offering the Blizzard PPC and CyberStorm PPC products. These boards had a unique dual-CPU design utilizing both a Motorola 68k processor and a higher performance PowerPC processor. They operated in a novel fashion where both CPUs could execute concurrently while sharing the system address space. This architecture was enforced by the fact that AmigaOS was still 68k-based at the time and the required ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PowerUP (accelerator)
PowerUP boards were dual-processor accelerator boards designed by Phase5 Digital Products for Amiga computers. They had two different processors, a Motorola 68000 series (68k) and a PowerPC, working in parallel, sharing the complete address space of the Amiga computer system. History In 1995, Amiga Technologies GmbH announced they were going to port AmigaOS to PowerPC. As part of their Power Amiga plan, Amiga Technologies was going to launch new Power Amiga models using the PowerPC 604e reduced instruction set computer (RISC) CPU and in cooperation with Amiga Technologies Phase5 would release AmigaOS 4-compatible PowerPC accelerator boards for old Amiga 1200, Amiga 3000 and Amiga 4000 models. However, in 1996 Amiga Technologies' parent company ESCOM entered into deep financial problems and could not support Amiga development. Due to a lack of resources, the PowerPC project at Amiga Technologies stalled and Phase5 had to launch accelerators without a PowerPC-native AmigaOS. As a s ...

MorphOS
MorphOS is an AmigaOS-like computer operating system (OS). It is a mixed Proprietary software, proprietary and Open-source software, open source OS produced for the Pegasos PowerPC (PPC) processor based computer, PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the Efika and mobileGT. Since MorphOS 2.4, Apple Inc., Apple's Mac Mini, Mac mini G4 is supported as well, and with the release of MorphOS 2.5 and MorphOS 2.6 the eMac and Power Mac G4 models are respectively supported. The release of MorphOS 3.2 added limited support for Power Mac G5. The core, based on the Quark (kernel), Quark microkernel, is proprietary, although several libraries and other parts are open source, such as the Ambient (desktop environment), Ambient desktop. Characteristics and versions Developed for PowerPC central processing units (CPUs) from Freescale and IBM it also supports the original AmigaOS Motorola 68000 series (68k ...

Library (computing)
In computer science, a library is a collection of non-volatile memory, non-volatile resources used by computer programs, often for software development. These may include configuration data, documentation, help data, message templates, Code reuse, pre-written code and subroutines, Class (computer science), classes, Value (computer science), values or Data type, type specifications. In OS/360 and successors, IBM's OS/360 and its successors they are referred to as Data set (IBM mainframe)#Partitioned datasets, partitioned data sets. A library is also a collection of implementations of behavior, written in terms of a language, that has a well-defined interface (computing), interface by which the behavior is invoked. For instance, people who want to write a higher-level program can use a library to make system calls instead of implementing those system calls over and over again. In addition, the behavior is provided for reuse by multiple independent programs. A program invokes the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Context Switch
In computing, a context switch is the process of storing the state of a process or thread, so that it can be restored and resume execution at a later point, and then restoring a different, previously saved, state. This allows multiple processes to share a single central processing unit (CPU), and is an essential feature of a multitasking operating system. The precise meaning of the phrase "context switch" varies. In a multitasking context, it refers to the process of storing the system state for one task, so that task can be paused and another task resumed. A context switch can also occur as the result of an interrupt, such as when a task needs to access disk storage, freeing up CPU time for other tasks. Some operating systems also require a context switch to move between user mode and kernel mode tasks. The process of context switching can have a negative impact on system performance. Cost Context switches are usually computationally intensive, and much of the design of opera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OS/2 Warp
OS/2 (Operating System/2) is a series of computer operating systems, initially created by Microsoft and IBM under the leadership of IBM software designer Ed Iacobucci. As a result of a feud between the two companies over how to position OS/2 relative to Microsoft's new Windows 3.1 operating environment, the two companies severed the relationship in 1992 and OS/2 development fell to IBM exclusively. The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "IBM Personal System/2, Personal System/2 (PS/2)" line of second-generation personal computers. The first version of OS/2 was released in December 1987 and newer versions were released until December 2001. OS/2 was intended as a protected mode, protected-mode successor of IBM PC DOS, PC DOS. Notably, basic system calls were modeled after MS-DOS calls; their names even started with "Dos" and it was possible to create "Family Mode" applications – text mode ap ...
