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 ...
For this reason, the IBM PowerPC desktops did not ship, although the reference design (codenamed Sandalbow) based on the PowerPC 601 CPU was released as an RS/6000 model (Byte ' s April 1994 issue included an extensive article about the Apple and IBM PowerPC desktops). Apple, which also lacked a PowerPC based OS, took a different route.
The first RS/6000 CPU has 2 configurations, called the "RIOS-1" and "RIOS.9" (or more commonly the POWER1 CPU). A RIOS-1 configuration has a total of 10 discrete chips: an instruction cache chip, fixed-point chip, floating-point chip, 4 data L1 cache chips, storage control chip, input/output chips, and a clock chip. The lower cost RIOS.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 .
The PowerPC 7xx is a family of third generation 32-bit PowerPC microprocessors designed and manufactured by IBM and Motorola (spun off as Freescale Semiconductor bought by NXP Semiconductors). This family is called the PowerPC G3 by Apple Computer (later Apple Inc.), which introduced it on November 10, 1997. A number of microprocessors from ...
These microprocessors implement the "Amazon", or "PowerPC-AS", instruction set architecture (ISA). Amazon is a superset of the PowerPC instruction set, with the addition of special features not in the PowerPC specification, mainly derived from POWER2 [citation needed] and the original AS/400 processor, and has been 64-bit from the start.
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 ...
PowerQUICC is the name for several PowerPC- and Power ISA-based microcontrollers from Freescale Semiconductor.They are built around one or more PowerPC cores and the Communications Processor Module (QUICC Engine) which is a separate RISC core specialized in such tasks such as I/O, communications, ATM, security acceleration, networking and USB.
