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.
The new instruction set architecture was called Power ISA and merged the PowerPC v.2.02 from the POWER5 with the PowerPC Book E specification from Freescale as well as some related technologies like the Vector-Media Extensions known under the brand name AltiVec (also called VMX by IBM) and hardware virtualization. This new ISA was called 'Power ...
Since 1991, IBM had a long-standing desire for a unifying operating system that would simultaneously host all existing operating systems as personalities upon one microkernel. From 1991 to 1995, the company designed and aggressively evangelized what would become Workplace OS, primarily targeting PowerPC. [2]: 290–291
The PCIe Root Complex holds a master copy of a 'Type 1 Configuration Table' that defines the host memory space that is accessible from each Endpoint device. In addition, each PCIe Endpoint device holds a master copy of their own memory space map in the host system memory as a 'Type 0 Configuration Table', this configuration table in each device ...
libtorrent is an open-source implementation of the BitTorrent protocol. It is written in and has its main library interface in C++.Its most notable features are support for Mainline DHT, IPv6, HTTP seeds and μTorrent's peer exchange. libtorrent uses Boost, specifically Boost.Asio to gain its platform independence.
Common Hardware Reference Platform (CHRP) is a standard system architecture for PowerPC-based computer systems published jointly by IBM and Apple in 1995. Like its predecessor PReP, it was conceptualized as a design to allow various operating systems to run on an industry standard hardware platform, and specified the use of Open Firmware and RTAS for machine abstraction purposes.
The Power Processing Element (PPE) comprises a Power Processing Unit (PPU) and a 512 KB L2 cache.In most instances the PPU is used in a PPE. The PPU is a 64-bit dual-threaded in-order PowerPC 2.02 microprocessor core designed by IBM for use primarily in the game consoles PlayStation 3 and Xbox 360, but has also found applications in high performance computing in supercomputers such as the ...
