	BDTI - GPP: Motorola/IBM PowerPC 604/604e
		The PowerPC 604e is an enhanced version of the PowerPC 604 and can operate at a clock speed of 225 MHz with a 2.5-volt supply for the processor core and a 3.3-volt supply for I/O. PowerPC 604 processors are manufactured and sold by Motorola and IBM Microelectronics and are being licensed to other vendors.
		The PowerPC 604 and PowerPC 604e are implementations of the PowerPC architecture specification, jointly developed by Apple, IBM, and Motorola.
		The fact that the PowerPC 604 processor is available from two major vendors and is being licensed to others is an advantage for this processor.

	PowerPC - Wikipedia, the free encyclopedia
		PowerPC is a RISC microprocessor architecture created by the 1991 Apple–IBM–Motorola alliance, known as AIM.
		PowerPC is largely based on IBM's earlier POWER architecture, and retains a high level of compatibility with it; the architectures have remained close enough that the same programs and operating systems will run on both if some care is taken in preparation; newer chips in the POWER series implement the full PowerPC instruction set.
		The PowerPC chip was one of several joint ventures involving the three, in their efforts to counter the growing Microsoft-Intel dominance of personal computing.

	A programmer's view of performance monitoring in the PowerPC microprocessor
		Features of the 604e PM The PM support in the first release of the 604 is described in its user manual [1], which documents a two-counter implementation with 40 unique events.
		Since the PM facility was not included in the PowerPC architecture at the time of development of the 604 and the 620, a significant interface difference occurred in the PM facility between the 32-bit word processors and the 64-bit word processors.
		The current PowerPC performance monitors allow the sample rate to be selected by the application by allowing a counter to be set to a value which causes the counter to go negative after some number of occurrences of an event (e.g., after one thousand cycles).

		When I agreed to look into the task, what I grasped was that the PowerPC family tree is more like a family jungle, with different variants on different processors combining with other lines to give rise to yet more processors, all for an array of markets that ranges from mainframes to routers to game consoles.
		Thus the AIM (Apple, IBM, Motorola) alliance was born, and with it was also born a subset of the POWER architecture dubbed PowerPC.
		PowerPC processors were to be jointly designed and produced by IBM and Motorola with input from Apple, and were to be used in Apple computers and in the embedded market.

		The 604e built on gains made by the 604 with a few core changes that included a doubling of the L1 cache sizes (32K instruction/32K data) and the addition of a new functional unit: the condition register unit (CRU).
		The 604e sports a functional block in its execution core that's dedicated to handling condition register logical operations, which means that these not uncommon operations don't tie up execution units — like the integer unit or the branch unit — that have other, more serious work to do.
		The 604e was ultimately able to scale up to 350MHz once it moved from an 0.35 to an 0.25 micron process.

	PowerPC Processor Roadmap
		The PowerPC 601 processor was the first produced by the motorola / IBM joint venture.
		All PowerPC's use a trick known as Superscalar-which is basically the CPU trying to do multiple instructions at one time.
		The end result of the improvements is that the 604e is about 14% faster (integer) and about 24% faster at (floating point) than the 604 at the same clock rate, and it is available in faster flavors.

		At the heart of the current high-end Macs, routers, and switches is the PowerPC G4, which is what Apple and Motorola claim to be their fourth generation CPU that is the result of the three-way Apple/IBM/Motorola alliance, which has been designing and fabbing various PowerPC chips since 1991.
		Why they decided to use the 603 core to continue the PowerPC line is not clear¹⁰ — obviously, the 603's unimpressive performance was well-known by all at all levels of Motorola and Apple.
		The PowerPC 604e debuted and proved to be cheaper, cooler, and faster than the 620.

		While it is faster than the early PowerPC processors, it is not as fast as the 620 is projected to be.
		The PowerPC architecture has a group of byte-reversing load and store instructions which might be useful for emulating little-endian x86 processors on a big-endian PowerPC system (such as an RS/6000 or a Power Macintosh).
