  Debian -- PowerPC Port
PowerPC support in the Linux kernel is now developed as part of the `main' Linux kernel at kernel.org.
The Debian PowerPC port began in 1997 at the German Linux Congress in Würzburg.
A PowerPC machine (Motorola StarMax 4000, 200 MHz 604e) was donated to the Debian project.

  PowerPC - Wikipedia, the free encyclopedia
PowerPC is a RISC microprocessor architecture created by the 1991 Apple-IBM-Motorola alliance, known as AIM.
PowerPC was the cornerstone of AIM's PReP and Common Hardware Reference Platform initiatives in the 1990s, but the architecture found the most success in the personal computer market in Apple's Macintosh lines from 1994-2006.
PowerPC is largely based on IBM's earlier POWER architecture, and retains a high level of compatibility with it; the architectures have remained close enough that the same programs and operating systems will run on both if some care is taken in preparation.

The history of the PowerPC begins with IBM's POWER architecture, introduced with the RISC System/6000 in early 1990.
An interesting side-effect of this implementation is that a program can store a 64-bit value (the longest operand format) to an address A while in one endian mode, switch modes, and when the value is read back from A it will be identical, even though ostensibly the processor is now in the opposite byte-order mode.
PowerPC processors are used in Apple Macintosh, IBM RS/6000 computer, the Pegasos (an Amiga spin off), Amiga acceleration boards, the Nintendo GameCube, and many embedded systems such as TiVo.

 Power Pc
PowerPcs don't need heatsinks the side of bricks, zillions of fans, or any of the other ways that Intel (as well as AMD and other x86-clone makers) use to cool CPUs that consume more power than some light bulbs out there.
One major annoyance with the PowerPc is that the usual convention for assigning numbers to bits is backwards.
In PowerPc collateral, bit 0 is the MSB, and bit 31 is the LSB (on a 32-bit architecture).

 PowerPC design services
To streamline the process of embedding PowerPC 4XX cores in SoCs, Cadence® offers a comprehensive set of consulting services, including a new custom-synthesized design approach that delivers up to a 30 percent increase in processor speed and a 40 percent reduction in chip area.
It advances PowerPC portability in markets such as consumer electronics and networking, where a full-synthesis approach may not yield the desired processor speed and area, but where time-to-market constraints prohibit employing a full-custom approach.
PowerPC projects currently underway include the 440 core implemented in 90 and 65nm processes, with initial customer discussions underway for implementing the same core targeted at 45nm.

 RS/6000 and PowerPC Options
IBM RS/6000 and PowerPC Options ------------------------------- These `-m' options are defined for the IBM RS/6000 and PowerPC: `-mpower' `-mno-power' `-mpower2' `-mno-power2' `-mpowerpc' `-mno-powerpc' `-mpowerpc-gpopt' `-mno-powerpc-gpopt' `-mpowerpc-gfxopt' `-mno-powerpc-gfxopt' GNU CC supports two related instruction set architectures for the RS/6000 and PowerPC.
For example, by default a structure containing nothing but 8 `unsigned' bitfields of length 1 would be aligned to a 4 byte boundary and have a size of 4 bytes.
Otherwise, the compiler must insert an instruction before every non prototyped call to set or clear bit 6 of the condition code register (CR) to indicate whether floating point values were passed in the floating point registers in case the function takes a variable arguments.

 PowerPC on Apple: An Architectural History, Part I: Page 1
When I agreed to look into the task, what I grasped was that the PowerPC family tree is more like a family jungle, with different variants on different processors combining with other lines to give rise to yet more processors, all for an array of markets that ranges from mainframes to routers to game consoles.
Besides, the fact that I'm a relative late-comer to the Mac platform means that I didn't follow the ins and outs of the AIM/PPC saga first-hand, so I'm not the most qualified person to write the kind of detailed history of it that does indeed deserve to be written.
PowerPC processors were to be jointly designed and produced by IBM and Motorola with input from Apple, and were to be used in Apple computers and in the embedded market.

PowerPC programs are usually larger than their 680x0 cousins, so the likelihood of a user's enabling virtual memory on a PowerPC machine is much higher than on an earlier Macintosh.
These dcmds were created by the PowerPC development team to aid in the construction of Macintosh with PowerPC and are provided on this issue's CD in a completely unsupported and barely documented fashion.
PowerPC code is bigger than the equivalent 680x0 code because all instructions are four bytes long to make things easier for the hardware.

 What is PowerPC? - a definition from Whatis.com - see also: power PC
PowerPC is a microprocessor architecture that was developed jointly by Apple, IBM, and Motorola.
The timing for the processor can then be based on simpler and faster operations, enabling the microprocessor to perform more instructions for a given clock speed.
The PowerPC architecture provides an alternative to the popular processor architectures from Intel, including the Pentium.

 [No title]
Motorola's head PowerPC spin-paramedic, director of PowerPC marketing Will Swearingen, said those claims were completely untrue, and that the company was still on course to roll-out the PowerPC G4, aka the PowerPC 7400, in volume around about the middle of this year.
IBM originally announced the PowerPC 750CXe in May of 2000, along with the PowerPC 750CX, but appears to be relaunching the processors today with changes to the specs from the earlier announcement.
The chip, the PowerPC G4+, was announced last month at Microprocessor Forum, and is the product of a major attempt by Motorola to catch up with the x86 world's lead in megaHertz.

 Synopsys - DesignWare IP -- IBM PowerPC 4xx Star IP Cores
These changes allow the PowerPC cores, CoreConnect peripherals, and the vast body of PowerPC software to be integrated with other application-specific logic on an SoC to create products and applications that have not previously used the Power Architecture.
In addition to the PowerPC DesignWare Star IP components, Synopsys provides SystemC models for the PowerPC processors and a broad range of CoreConnect peripherals as a standard part of its System Studio product, allowing system level designers to explore high-level architectural alternatives and analyze the performance and functionality of their designs.
Synopsys is a founding member of Power.org, a multi-industry collaboration to develop open standards and specifications, business guidelines documents, best practices and education, certifications to validate implementations and drive adoption of Power Architecture technology.

 penguinppc.org: Introduction to PowerPC Linux
When Power.org was formed, IBM decided that "PowerPC" sounded too much like "personal computer", a market PowerPC vendors were abondoning to x86 processors.
PowerPC Linux is the Linux kernel running on a PowerPC processor.
PowerPC GNU/Linux runs natively on PCI-based Apple Power Macintosh, many IBM and Motorola PReP and CHRP workstations, IBM pSeries and iSeries servers, Amiga Power-UP systems, and many embedded platforms that utilize the Motorola/Freescale and IBM/AMCC embedded PowerPC processors.

If the PowerPC is to retain any credibility as an alternative to the x86, the alliance must deliver a steady stream of faster chips and a viable system standard that attracts big-volume vendors.
The PowerPC platform carries some baggage from both the existing PC architecture and the Mac because it's designed to work with industry standard PC components and Mac peripherals.
The PowerPC is the best-selling RISC architecture on the desktop, but almost all PowerPC systems are Power Macs, and Apple has less than 9 percent of the market.
