Motorola & IBM’s PowerPCOverview of
Wesley Davis
IBM’s first attempts at RISC
• PC/RT workstation– ROMP CPU
• POWER architecture
Motorola + IBM+ Apple
• Designed PowerPC architecture
• PowerOpen Environment specification
• Apple & IBM: Taligent– OS for PowerOpen spec & PowerPC– Disbanded in 1995
• Common Hardware Reference Platform (CHRP)
First-Generation PowerPC (G1)
• First PowerPC chip produced: 601– Apple PowerMac 6100– IBM RS/6000
• Embedded applications:– IBM 4xx, Motorola 5xx, 8xx
Second-Generation (G2)
• Desktop/Servers: 602, 603, 604, 620– 603e, 604e: first 200MHz desktop CPU– 620: 64-bit server CPU– 603q & x704: third-party G2 processors
• Embedded applications:– 5xxx, 82xxx, E603e– E603e: first 300MHz embedded CPU
Third-Generation (G3)
• Desktop/Servers: 750, 755– 750: world’s first copper-based CPU– 750FX: first 1000MHz CPU– Multiprocessing capable
• Embedded applications: 740, 745– 740: First 400MHz embedded CPU– 740: First copper-based embedded CPU
Forth-Generation (G4)
• 74xx series
• Copper-based
• Multiprocessor configurations
• AltiVec Technology / Velocity Engine– Answer to Intel’s MMX– Vector math unit on CPU– 160 new instructions for PowerPC ISA
Fifth-Generation (G5)
• PPC 8500
• 64-bit clean
• Copper-based
• Silicon-On-Insulator (SOI) design
• Multiprocessor configurations
• AltiVec Technology
Apple Computer
• PowerMac– 601, 603, 604, G3, G4
• PowerBook– 601, 603, 604, G3, G4
• iMac– First series: G3– Second series: G4
• iBook– G3
BeBox
• Dual 603– 66MHz and 133MHz configurations– Custom hardware/software for MP on 603
• 603 did not natively support MP
• PC-style hardware– ISA bus, PCI bus
• Modems, network adaptors, video cards, sound
– AT-keyboard (no ADB)
Nintendo GameCube
• “Gekko”– Custom 405MHz PowerPC processor
Operating Systems
• Apple MacOS
• Microsoft Windows NT
• BeOS
• IBM AIX, OS/2
• BSD
• Linux
• Others…
Apple MacOS
• Version 7:– First to support PowerPC Macintosh
• Version 8:– New GUI, 8.5 was first to be PPC-only
• Version 9:– Further GUI improvements
• Version 10:– Rewritten OS: Darwin BSD core
Microsoft Windows NT
• NT 3.51 and 4.0
• Platform support:– Intel x86– PowerPC– DEC Alpha– MIPS
BeOS
• Designed for dual-603 BeBoxes
• Released for other PowerPC machines– Apple would not give G3 specs
• BeOS developed for x86
• Be, Inc. now out of business– Sold property and materials to Palm, Inc.
IBM
• AIX– Basis of PowerOpen spec– Ported to IBM PowerPCs and PowerMacs
• OS/2– IBM desktop OS, also for x86– Developed with Microsoft
• Basis for Windows NT
UNIX-like operating systems
• BSD– FreeBSD, NetBSD, OpenBSD
• Supports many hardware platforms
– Apple Darwin: core of MacOS X• Ported to x86
• Linux– Originally designed for x86
• Support for almost any hardware platform
– LinuxPPC, MkLinux, Linux-Mandrake PPC
Other operating systems
• QNX Neutrino
• AmigaOS
• LynxOS
• ChorusOS
• PowerMAX OS
• OS-9
Real-Time Embedded OS
• VRTX
• Nucleus
Benchmarks
• BYTEmark
• SPEC95
