Northbridge or host bridge for PowerPC CPU is an Integrated Circuit (IC) for interfacing PowerPC CPU with memory, and Southbridge IC. Some Northbridge also provide interface for Accelerated Graphics Ports (AGP) bus, Peripheral Component Interconnect (PCI), PCI-X, PCI Express, or Hypertransport bus.
A typical north/southbridge layout (2015) A typical north/southbridge layout (2007) In computing, a northbridge (also host bridge, or memory controller hub) is a microchip that comprises the core logic chipset architecture on motherboards to handle high-performance tasks, especially for older personal computers.
In this case, it is PowerPC and Power ISA, processor architectures initially developed in the early 1990s by the AIM alliance, i.e. Apple, IBM, and Motorola. Even though these consoles share much in regard to instruction set architecture , game consoles are still highly specialized computers so it is not common for games to be readily portable ...
PReP-compliant systems will be able to run OS/2, AIX, Solaris, Taligent, and Windows NT; and the CHRP (Common Hardware Reference Platform) is an open platform agreed on by Apple, IBM, and Motorola. All CHRP systems will be able to run Mac OS, OS/2-PPC, Windows NT, AIX, Solaris, Novell Netware. CHRP is a superset of PReP and the PowerMac platforms.
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 ...
To Apple, the performance of the PowerPC was a bright spot in the face of increased competition from Windows 95 and Windows NT-based PCs. With the cancellation of Workplace OS, the general PowerPC platform (especially AIM's Common Hardware Reference Platform ) was instead seen as a hardware-only compromise to run many operating systems one at a ...

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 .
