Plataforma de Referência PowerPC (PowerPC … Plataforma de Referência PowerPC (PowerPC Reference Platform/PReP) é uma arquitetura de sistema padrão para PowerPC desenvolvida ao mesmo tempo que a arquitetura do processador PowerPC. Publicado em 1994 pela IBM, ela permitiu que os fabricantes de hardware pudessem construir máquinas que pudessem ser compatíveis com muitos sistemas operacionais, como Windows NT, OS/2, Solaris, e AIX. Um dos objetivos da especificação PReP era prover um padrão de hardware de PC, e assim o PReP era essencialmente um PC clone com CPU PowerPC. A Apple Inc. querendo a transição de seus computadores para a nova plataforma PowerPC achou o PReP problemático. Assim, uma nova versão do PReP, chamada Plataforma de Referência de Hardware Comum(Common Hardware Reference Platform/CHRP), incluindo a arquitetura Power Macintosh foi publicada mais tarde em 1995. Sistemas baseados em PReP nunca foram populares e os fabricantes que realmente lançavam produtos eram a IBM e a Motorola. Achar sistemas operacionais para essas plataformas também era problemático (existem portes de Linux da Debian e NetBSD compatíveis). Power.org tem uma nova especificação, chamada Plataforma de Referência da Arquitetura Power (Power Architecture Platform Reference/PAPR), que provê a fundação para o desenvolvimento da arquitetura Power com computadores equipados de sistema Linux. PAPR foi lançado no quarto trimestre de 2006.R foi lançado no quarto trimestre de 2006.
, PowerPC Reference Platform (PReP) è una se … PowerPC Reference Platform (PReP) è una serie di specifiche tecniche sviluppate per consentire la realizzazione di computer basati su processori PowerPC. Le specifiche furono realizzate con quando il progetto PowerPC stava per mettere sul mercato il primo processore della serie. Le specifiche avrebbero consentito ai produttori hardware di realizzare delle macchine standard in grado di eseguire molti sistemi operativi, in particolare le specifiche prevedevano il supporto per il Mac OS, Windows NT Solaris, AIX e altri Unix commerciali. I sistemi PReP non furono mai popolari, solo alcune macchine RS/6000 basate su AIX seguirono le specifiche. Il specifiche PReP intendeva realizzare una serie di cloni PC basati su PowerPC. Apple Computer riteneva le specifiche troppo pc centriche, in particolare la presenza della porta parallela obbligatoria era ritenuta molto odiosa, i computer Apple non avevano mai avuto porte parallele e nessun programma o periferica l'avrebbe utilizzata. Apple quindi in sostanza decise di non seguire lo standard. Dato lo scarso supporto allo standard e le molte critiche venne varato lo standard CHRP, uno standard basato su Open Firmware, molto più flessibile nella dotazione hardware e quindi più adatto alle richieste Apple. Attualmente trovare sistemi operativi che supportino computer basati su PReP e molto difficile. Solo la Debian e NetBSD riconoscono questa architettura e gestiscono le periferiche ma il supporto reale è molto ridotto dato il basso numero di macchine esistenti. Power.org lavora alle specifiche Power Architecture Platform Reference (PAPR), le nuove specifiche dovrebbero fornire un fondamento comune per la macchine basate su architettura Power. la macchine basate su architettura Power.

Architektura ta miała pozwolić producentom sprzętu na stworzenie własnych rozwiązań, które pozwoliłyby na uruchomienie różnych systemów operacyjnych, takich jak Mac OS, Windows NT oraz systemów operacyjnych z rodziny UNIX, w szczególności Sun Solaris i AIX. Systemy zgodne z architekturą PReP nigdy nie zdobyły zakładanej przez twórców popularności, a jedynymi rozwiązaniami z nią zgodnymi były serwery IBM RS/6000 wraz z dostarczanym dla nich systemem operacyjnym AIX. PReP, pomimo intencji twórców, był odpowiednikiem architektury komputerów klasy PC dla mikroprocesora PowerPC. W związku z niektórymi, dosyć zaskakującymi wymaganiami architektury (np. wymagania dotyczące portu standardu Centronics), Apple nigdy nie zaczęto stosować tego standardu. W momencie, w którym uświadomiono sobie, że nikt nie jest zbyt zadowolony z architektury PReP, stworzono nowy standard architektury pod nazwą CHRP. Kluczową sprawą w architekturze CHRP stało się użycie Open Firmware'u, co dostarczyło twórcom rozwiązań komputerowych znacznie lepszego wsparcia podczas procesu startu systemu (bootowania) i procedur dostępu do warstwy sprzętowej. i procedur dostępu do warstwy sprzętowej.
, PowerPC Reference Platform (PReP) was a st … PowerPC Reference Platform (PReP) was a standard system architecture for PowerPC-based computer systems (as well as a reference implementation) developed at the same time as the PowerPC processor architecture. Published by IBM in 1994, it allowed hardware vendors to build a machine that could run various operating systems, including Windows NT, OS/2, Solaris, Taligent and AIX. One of the stated goals of the PReP specification was to leverage standard PC hardware. Apple, wishing to seamlessly transition its Macintosh computers to PowerPC, found this to be particularly problematic. As it appeared no one was particularly happy with PReP, a new standard, the Common Hardware Reference Platform (CHRP), was developed and published in late 1995, incorporating the elements of both PReP and the Power Macintosh architecture. Key to CHRP was the requirement for Open Firmware (also required in PReP-compliant systems delivered after June 1, 1995), which gave vendors greatly improved support during the boot process, allowing the hardware to be far more varied. PReP systems were never popular. Finding current, readily available operating systems for old PReP hardware can be difficult. Debian and NetBSD still maintain their respective ports to this architecture, although developer and user activity is extremely low. The RTEMS real-time operating system provides a board support package for PReP which can be run utilizing the QEMU PReP emulator. This provides a convenient development environment for PowerPC-based real-time, embedded systems. Power.org has a Power Architecture Platform Reference (PAPR) that provides the foundation for development of Power ISA-based computers running the Linux operating system. PAPR was released in the fourth quarter of 2006.as released in the fourth quarter of 2006.
