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 ef="module.php?name=Lexikon&file=search&eid=1&query=POWeR">POWeR architecture, used in IBM' s ef="module.php?name=Lexikon&file=search&eid=1&query=RS/6000">RS/6000 ef="module.php?name=Lexikon&file=search&eid=1&query=workstation">workstations. Currently ef="module.php?name=Lexikon&file=search&eid=1&query=IBM">IBM and ef="module.php?name=Lexikon&file=search&eid=1&query=Motorola">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 ef="module.php?name=Lexikon&file=search&eid=1&query=registers">registers (32- or 64 bit) and 32 ef="module.php?name=Lexikon&file=search&eid=1&query=floating-point">floating-point (Ieee standard 64 bit) ef="module.php?name=Lexikon&file=search&eid=1&query=floating-point">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 ef="module.php?name=Lexikon&file=search&eid=1&query=little-endian">little-endian mode. Addition of single precision ef="module.php?name=Lexikon&file=search&eid=1&query=floating-point">floating-point operations. Control of branch prediction direction. A hardware coherency model (not in Book I). Some other ef="module.php?name=Lexikon&file=search&eid=1&query=floating-point">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).
