由IBM公司与Motorola公司推出一种RISC微处理器

(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).
