PPC
(PPC) A RISC microprocessor designed
to meet a standard which was jointly designed by Motorola,
IBM, and Apple Computer (the PowerPC Alliance). The
PowerPC standard specifies a common {instruction set
architecture} (ISA), allowing anyone to design and fabricate
PowerPC processors, which will run the same code. The PowerPC
architecture is based on the IBM POWER architecture, used in
IBM's RS/6000 workstations. Currently IBM and
Motorola are working on PowerPC chips.
The PowerPC standard specifies both 32-bit and 64-bit data
paths. Early implementations were 32-bit (e.g. {PowerPC
601}); later higher-performance implementations were 64-bit
(e.g. PowerPC 620). A PowerPC has 32 integer registers (32-
or 64 bit) and 32 floating-point (IEEE standard 64 bit)
floating-point registers.
The POWER CPU chip and PowerPC have a (large) common core, but
both have instructions that the other doesn't. The PowerPC
offers the following features that POWER does not:
Support for running in little-endian mode.
Addition of single precision floating-point operations.
Control of branch prediction direction.
A hardware coherency model (not in Book I).
Some other floating-point instructions (some optional).
The real time clock (upper and lower) was replaced with the
time base registers (upper and lower), which don't count in
sec/ns (the decrementer also changed).
64-bit instruction operands, registers, etc. (in 64 bit
processors).
See also PowerOpen, PowerPC Platform (PReP).

PPCP
(PPCP, PReP - PowerPC Reference
Platform, formerly CHRP - Common Hardware Reference Platform)
An open system standard, designed by IBM, intended to ensure
compatibility among PowerPC-based systems built by different
companies. The PReP standard specifies the PCI bus, but
will also support ISA, MicroChannel and PCMCIA.
PReP-compliant systems will be able to run the Macintosh OS,
OS/2, WorkplaceOS, AIX, Solaris, Taligent and
Windows NT. IBM systems will (of course) be PReP-compliant.
Apple's first PowerPC Macintoshes will not be compliant,
but future ones may be.
