Apple, IBM, Microsoft, Novell, and SunSoft are planned to support the PowerPC
Platform.
The PowerPC Platform, combined with the superior performance of the PowerPC
RISC microprocessor, will support today's advanced applications and drive the next
generation of applications which address emerging customer requirements for
video, multimedia, virtual reality, speech recognition, 3D graphics, and enhanced
communications. PowerPC Platform-compliant systems will also benefit from the
availability of components designed to industry specifications which can help
reduce costs.
The PowerPC Platform specification is a blueprint for system vendors and
independent hardware vendors. It specifies the kinds of input/output interfaces, bus
standards and other system-level functional elements required to implement a
single, unified architecture around the PowerPC microprocessor. The PowerPC
alliance companies: Apple, IBM and Motorola, are publishing the PowerPC Platform
specifications as part of their initiative to create a superior, industry-wide
RISC-based alternative to the CISC-based X86 offerings. The PowerPC Platform
provides a standard architecture for the next generation of personal computing - an
architecture that is open, multi-OS capable, scalable from portables to
high-performance servers, and free from the limitations of CISC-based
microprocessor architectures, which have had to incorporate RISC-like features to
avoid reaching their performance peak.
The PowerPC Platform, an open, publicly available reference architecture for the
industry, leverages industry standard component designs. System vendors
choosing to implement the PowerPC Platform will benefit not only from the
specifications but also from the reference designs and infrastructure, including
chipsets, peripherals and firmware from leading vendors. Thus, the PowerPC
Platform provides a lower-cost, standard PC foundation for a broad range of
computing systems from multiple system vendors which can help to increase PC
volumes and enables system vendors to differentiate their PowerPC systems.
Additionally, users will benefit from broader access to software applications.
PowerPC Platform Document
The PowerPC Platform document is a superset of the PowerPC Reference
Platform Specification, Version 1.1, the Apple RISC Architecture (Power
Macintosh) and IBM RISC server systems.
1.3.3 PowerPC Platform Goals
The goals of this specification are as follows:
To create an open industry standard to be used for the implementation of
PowerPC-based systems. The architecture document is available to the
industry and can be used by any hardware or software vendor to develop
compliant products.
To allow compatible differentiation through the use of abstracted hardware
interfaces, defined minimum hardware, and extension mechanisms.
To leverage existing and future industry-standard buses and interfaces.
Existing bus architectures have a proven level of performance and functionality.
Established industry-standard interfaces (SCSI, IDE, LocalTalk, Ethernet, and
