| PowerPC G4 is a designation used by Apple Computer to describe a fourth generation of PowerPC microprocessors.Apple has applied this name to various different (though closely related) processor models from Freescale, a former part of Motorola.Macintosh computers such as the PowerBook G4 and iBook G4 laptops and the Power Mac G4 and Power Mac G4 Cube desktops all took their name from the processor.Mac before the introduction of the G5 processor.PowerPC 970 processor as the basis for its PowerPC G5 series.The last desktop model that used the G4 was the Mac mini which now comes with an Intel processor.The PowerPC G4 processors are also popular in other computer systems, such as Amiga clones, like the Pegasos from Genesi.Besides desktop computers the PowerPC G4 is popular in embedded environments, like routers, telecom switches, imaging, media processing, avionics and military applications, where one can take advantage of the AltiVec and its SMP capabilities."Apollo 7"

8.PowerPC 7400
The 7400 (Codename: Max) debuted in late summer of 1999 and was the first processor to carry the G4 moniker.The chip operates at speeds ranging from 350 to 500 MHz and contains 10.Motorola had promised Apple to deliver parts with speed up to 500 MHz, but yields proved too low initially.This forced Apple to take back the advertised 500 MHz models of PowerMac G4.Motorola relationship, and reportedly caused Apple to ask IBM for assistance to get the production yields up on the Motorola 7400 series line.MHz model was reintroduced on February 16, 2000.AltiVec, for which IBM reused the old 7400 design they still had from the design they did with Motorola in Somerset.Furthermore, the vector processing unit is superscalar, and can do two vector operations at the same time.Some examples are Adobe Photoshop which utilises the AltiVec unit for faster rendering of effects and transitions, and Apple's iLife suite which takes advantage of the unit for importing and converting files on the fly.Devices that utilizes the 60x bus can be made compatible with either G3 or G4 processors, enabling a wide variery of offerings and a clear and cheap upgrade path while keeping compatibility issues at a minimum.Like the 7400 it has 10.PowerBook G4, introduced on January 9, 2001.The feature was used by embedded systems vendors such as Mercury Computer Systems.The PowerPC 7450 was the only major redesign of the G4 processor.L2 cache, and introduced external L3 Cache (up to 2 MiB).AltiVec instructions at the same time.MHz Power Mac G4 on January 9, 2001.The enhancements to the 745x design gave it the nicknames G4e or G4+ but these were never official designations.The 7445 is the same chip without the L3 cache interface.The 7455 is used in the AmigaOne XE G4."Apollo 7"
As of early 2005 the fastest processor shipping in Apple's G4 lineup was the MPC 7447B, running at 1.GHz and found in the January 2005 revision PowerBooks.Cache and was manufactured at 130 nm, hence drawing less power.The 7457 has an additional L3 Cache interface.The only companies that offer the 7457 in the form of upgrades for the Power Mac G4 and Power Mac G4 Cube are Giga Designs, Daystar Technology (they use the 7457 only for iMac G4 upgrades) and PowerLogix.MiB L2 cache and up to 200 MHz front side bus and it features Freescale's new standard core, the e600.Daystar ships a 7448 upgrade for Aluminum PowerBook G4s, and NewerTech have similar upgrades for older PowerMac G4s.In 2004 Freescale renamed the G4 core e600 and changed focus from general CPUs to high end embedded SoC devices, and introduced a new naming scheme, MPC86xx.Products incorporating the e700 core will be named MPC87xx.This page was last modified 10:45, 1 January 2008.See Copyrights for details.The Power Mac G4 was a series of personal computers designed, manufactured, and sold by Apple between 1999 and 2004.It uses the PowerPC G4 (PPC74xx) series of microprocessors.White) computers (minus the ADB port), in a "graphite" colored case and with the new PowerPC 7400 (G4) CPU.In December 1999, the entire Power Mac G4 line was updated to the AGP motherboard.Announced in July 2000 the Power Macintosh G4 (Gigabit Ethernet) that added dual processors came to the lineup.It came with a 400 MHz, or dual 450 MHz, or 500 MHz Processors.The AGP Power Macs were the first to include an AirPort slot and DVI video port.Apple's name for all these early AGP models is Power Mac AGP Graphics.It was also the first personal computer to include Gigabit ethernet as standard.RAM and Zip drives were optional on all models.These models also introduced Apple's proprietary Apple Display Connector video port.Apple's name for this series is the Power Mac Gigabit Ethernet."Graphite" case debuted on 9 January 2001.New features included a fourth PCI slot, a 133 MHz system bus, an improved 4X AGP slot, and a new "digital audio" sound system, giving the series its name "Power Mac Digital Audio".The models were offered in 466 MHz, 533 MHz, dual 533 MHz, 667 MHz and 733 MHz configurations, the latter two using a newer PowerPC 7450 processor.The number of RAM slots were reduced to three, accommodating up to 1.At Macworld Expo New York on 18 July 2001, a new line debuted featuring a cosmetically redesigned case known as "Quicksilver", but only minor technical changes.Some of these models have ATA controllers with 48 bit LBA for hard drives larger than 128 GB.This later series is commonly known as Quicksilver 2002.GHz model would be the last Power Mac G4 the company offered to the public after the announcement of the new Power Mac G5, introduced in June 2003.The models were noted for their noisiness, earning them the unofficial designation "Windtunnel G4" in some circles.The last real update to the Power Mac G4 line was on 28 January 2003 offering dual 1.FireWire 800 connector, optional integrated Bluetooth, and optional integrated AirPort Extreme.These were also the first Power Macs that could not boot into Mac OS 9.August 2002 Power Mac G4 because of perceived demand for Mac OS 9 machines.See also: Apple hardware before 1998.All text is available under the terms of the GNU Free

processing applications.C4 compressor, AC 24 crossover, DEQ 60 and DEQ60L graphic equalizers, and the PEQ 55 parametric equalizer.Analog controls (knobs, sliders) allow a performer or sound engineer to make precise adjustments, in real time.Digital signal processing (DSP) provides a degree of accuracy, consistency and flexibility that simply can not be matched with a traditional analog design.The G4 combines the best of both worlds by using analog controls and high performance digital processing to achieve an unprecedented feature set.The G4 is ideal for a variety of dynamics applications including gating, ducking and downward expansion.The G4 is the only quad gate available with this complete set of features.The G4 uses a very short look ahead (16 samples, or 333 microseconds) with exponential ramping to ensure accurate clickless gating.The RPM Series of Drag Net products contain programmable gates, using the same DSP algorithms as the G4.Source for G4 News and Updates!NOTE: The
