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. Becaus ...

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 International, 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), PowerUP acceler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 (computer 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 PowerP ...

MorphOS
MorphOS is an AmigaOS-like operating system designed for Power and PowerPC based computers. The core, based on the Quark microkernel, is proprietary, although several libraries and other parts are open source, such as the Ambient desktop. The project began in 1999 and it was produced for the Pegasos computer, as well as PowerUP accelerator equipped Amiga computers, and a series of Freescale development boards that use the Genesi firmware, including the Efika and mobileGT. Since then MorphOS has been ported to Apple's Mac mini, eMac, Power Mac G4 and limited support for Power Mac G5. It is binary compatible with software written for Motorola 68k-based Amiga computers. History The project began in 1999, based on the Quark microkernel. The earliest versions of MorphOS ran only via PPC accelerator cards on the Amiga computers, and required portions of AmigaOS to fully function. A collaborative effort between the companies bPlan (of which the lead MorphOS developer is a pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Software
Application software is any computer program that is intended for end-user use not operating, administering or programming the computer. An application (app, application program, software application) is any program that can be categorized as application software. Common types of applications include word processor, media player and accounting software. The term ''application software'' refers to all applications collectively and can be used to differentiate from system and utility software. Applications may be bundled with the computer and its system software or published separately. Applications may be proprietary or open-source. The short term ''app'' (coined in 1981 or earlier) became popular with the 2008 introduction of the iOS App Store, to refer to applications for mobile devices such as smartphones and tablets. Later, with introduction of the Mac App Store (in 2010) and Windows Store (in 2011), the term was extended in popular use to include desktop a ...

Library (computing)
In computing, a library is a collection of System resource, resources that can be leveraged during software development to implement a computer program. Commonly, a library consists of executable code such as compiled function (computer science), functions and Class (computer programming), classes, or a library can be a collection of source code. A resource library may contain data such as images and Text string, text. A library can be used by multiple, independent consumers (programs and other libraries). This differs from resources defined in a program which can usually only be used by that program. When a consumer uses a library resource, it gains the value of the library without having to implement it itself. Libraries encourage software reuse in a Modular programming, modular fashion. Libraries can use other libraries resulting in a hierarchy of libraries in a program. When writing code that uses a library, a programmer only needs to know how to use it not its internal d ...

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 multiprogramming or multitasking operating system. In a traditional CPU, each process – a program in execution – uses the various CPU registers to store data and hold the current state of the running process. However, in a multitasking operating system, the operating system switches between processes or threads to allow the execution of multiple processes simultaneously. For every switch, the operating system must save the state of the currently running process, followed by loading the next process state, which will run on the CPU. This sequence of operations that stores the state of the running process and loads the following running process is called a ...

OS/2 Warp
OS/2 is a Proprietary software, proprietary computer operating system for x86 and PowerPC based personal computers. It was created and initially developed jointly by IBM and Microsoft, under the leadership of IBM software designer Ed Iacobucci, intended as a replacement for DOS. The first version was released in 1987. A feud between the two companies beginning in 1990 led to Microsoft’s leaving development solely to IBM, which continued development on its own. OS/2 Warp 4 in 1996 was the last major upgrade, after which IBM slowly halted the product as it failed to compete against Microsoft's Microsoft Windows, Windows; updated versions of OS/2 were released by IBM until 2001. 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 PCs. OS/2 was intended as a protected mode, protected-mode successor of IBM PC DOS, PC DOS targeting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
