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 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 2009, Microsoft released Windows Virtual PC, which is only compatible with Windows 7 hosts, [a] and is the technical foundation for the latter's Windows XP Mode. Windows Virtual PC does not officially support MS-DOS or operating systems older than Windows XP Professional SP3 as guests. [ 3 ]
For user-mode emulation, QEMU maps emulated threads to host threads. QEMU can run a host thread for each emulated virtual CPU (vCPU) for full system emulation. This depends on the guest being updated to support parallel system emulation, currently ARM, Alpha, HP-PA, PowerPC, RISC-V, s390x, x86, and Xtensa.
This was done so that PowerPC devices serving as co-processors on PCI boards could share data structures with host computers based on x86. Both PCI and x86 are little-endian. OS/2 and Windows NT for PowerPC ran the processor in little-endian mode while Solaris, AIX and Linux ran in big endian. [9]

It was initially launched in 2011 as part of Intel X79 for the desktop enthusiast Sandy Bridge-E processors in Waimea Bay platforms. [19] Patsburg was then used for the Sandy Bridge-EP server platform (the platform was codenamed Romley and the CPUs codenamed Jaketown, and finally branded as Xeon E5-2600 series) launched in early 2012.
