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. Specific Northbridge IC must be used for ...
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]

After two years of development, the resulting PowerPC ISA was introduced in 1993. A modified version of the RSC architecture, PowerPC added single-precision floating point instructions and general register-to-register multiply and divide instructions, and removed some POWER features. It also added a 64-bit version of the ISA and support for SMP.
Power ISA is an evolution of the PowerPC ISA, created by the mergers of the core PowerPC ISA and the optional Book E for embedded applications. The merger of these two components in 2006 was led by Power.org founders IBM and Freescale Semiconductor. Prior to version 3.0, the ISA is divided into several categories.

The PowerPC 602 was a stripped-down version of PowerPC 603, specially made for game consoles by Motorola and IBM, introduced in February 1995. [29] It has smaller L1 caches (4 KB instruction and 4 KB data), a single-precision floating-point unit [29] and a scaled back branch prediction unit. It was offered at speeds ranging from 50 to 80 MHz ...
