Specific Northbridge IC must be used for PowerPC CPU. It is impossible to use Northbridge for Intel or AMD x86 CPU with PowerPC CPU. However it is possible to use certain types of x86 Southbridge in PowerPC based motherboards. Example: VIA 686B and AMD Geode CS5536. Apple UniNorth 2 AGP used in PowerPC 74xx Based Macs
A common example of a northbridge on a PowerPC platform is in Apple's older PowerPC-based computers like the iMac G5, which utilized an IBM CPC945 Northbridge chip. According to an Apple Developer note, The Power Mac G5's northbridge chip connected to a "Mid Bridge", which then connected to a south bridge. [9]
The PowerPC 970, PowerPC 970FX, and PowerPC 970MP are 64-bit PowerPC CPUs from IBM introduced in 2002. Apple branded the 970 as PowerPC G5 for its Power Mac G5 . Having created the PowerPC architecture in the early 1990s via the AIM alliance , the 970 family was created through a further collaboration between IBM and Apple .
Book III-E – Defines the supervisor instructions used for embedded applications. It is derived from the former PowerPC Book E. Book VLE – Variable Length Encoded Instruction Architecture defines alternative instructions and definitions from Books I–III, intended for higher instruction density and very-low-end applications. They use 16-bit ...
Apple completely phased out the G4 series for desktop models after it selected the 64-bit IBM-produced PowerPC 970 processor as the basis for its PowerPC G5 series. The last desktop model that used the G4 was the Mac Mini. The last portable to use the G4 was the iBook G4, which was replaced by the Intel-based MacBook.
The PowerPC 400 family is a line of 32-bit embedded RISC processor cores based on the PowerPC or Power ISA instruction set architectures.The cores are designed to fit inside specialized applications ranging from system-on-a-chip (SoC) microcontrollers, network appliances, application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs) to set-top boxes, storage ...
The existing POWER and the upcoming PowerPC ISAs were deemed unsuitable by the AS/400 team so an extension to the 64-bit PowerPC instruction set was developed called PowerPC AS for Advances Series or Amazon Series. Later, additions from the RS/6000 team and AIM Alliance PowerPC were included, and by 2001, with the introduction of POWER4, they ...
Gekko is the IBM's custom central processor for the Nintendo GameCube game console. Based on a PowerPC 750CXe, it adds about 50 new instructions and a modified FPU capable of some SIMD functionality. It has 256 KiB of on die L2 cache, operates at 486 MHz with a 162 MHz memory bus, is fabricated by IBM on a 180 nm process.
