	PA-RISC family - Wikipedia, the free encyclopedia
		As the name implies, it is an implementation using a RISC design, where the PA stands for Precision Architecture.
		PA is considered by some to stand for Palo Alto, the location of HP's headquarters.
		One was the HP 9000 Unix workstations, designs based a proprietary HP CPU, built using a special Silicon-on-sapphire (SOS) technology, another on the Motorola 68000 family they had acquired when they purchased Apollo Computer.

	Real World Technologies - The Looming Battle in 64 Bit Land
		HP is officially in the same camp as SGI in that they have announced the intention of replacing their PA-RISC family with IA-64.
		Most of the flagship parts of the competing RISC processor families, along with the Merced/Itanium IA-64 processor, will be manufactured in 0.18 um technologies within the next six to twelve months.
		Curiously, both IBM and Compaq are planning the schizophrenic strategy of offering systems based on both IA-64 processors and their own respective RISC processors.

	HP sketches Itanium 2 chip set, system plans
		HP will deliver a dual-core PA 8800 chip that uses the Itanium 2 processor bus and runs at 1 GHz or faster next year, to be followed by the 8900, an updated version of that chip, in 2004.
		The PA 8900 "looks like the processor to retire the line on, so it has to last for a long time," said Crume.
		The 64-bit Itanium family has been criticized for its poor performance on native 32-bit X86 code.

		According to sources, HP is releasing its last chip in the PA/RISC family that powers its high-performance and high-availability network servers.
		Closing out this family is part of HP's plans to move its customer base to the Itanium platform, which HP co-designed with Intel in the 1990's.
		HP's PA/RISC chips have been powering HP Unix servers since the 1980's.

		By the way, Intel Corporation has a license from Advanced RISC Machines to produce, sell and enhance the StrongARM (developed by Digital Corporation, DEC has licensed the ARM architecture) microprocessor family.
		But on 14 Oct, 1997 at Microprocessor Forum ([3]) HP and Intel officials revealed that IA-64 family microprocessors would contain N replicated sets of three functional units and it is naturally to assume that such a set must contain one integer, one floating-point and one load/store units.

	Hewlett-Packard PA-RISC 8800
		The signals are somewhat confusing in that respect: sometimes is also stated that the PA-RISC family will stop at this latest PA-8800 chip (which we think to be more likely).
		Like all advanced RISC processors the PA-8700(+) has out-of-order execution, the sequence of instructions being determined by the instruction reorder buffer (IRB) which contains an ALU buffer that drives the computational functional units and a memory buffer that controls the load/store units.
		According to HP's roadmap at least one new generation of the PA-8x00 family is projected: the PA-8900 that will be on the market concurrently with the IA-64 Itanium Montecito.

		This enhancement to the typical RISC instruction set was a direct result of research by HP for a processor design optimized over the full range of technical and commercial applications.
		It was one of the first commercially available RISC processors, including the fixed-size, hardware-inspired instructions common to RISC designs, but also including additional instructions for manipulating strings and other data types used in commercial processing.

	HP to ship powerful copper chip next year CNET News.com
		The 8700 is part of HP's two-pronged strategy to advance its own PA-RISC chips while adding Intel's upcoming IA-64 chip family into the HP product line.
		HP helped develop the architecture behind the IA-64 chips but has at least two more generations of PA-RISC chips after the 8700 under design.
		The next, McKinley, is expected a year later and is widely regarded as a more serious contender because companies will have had more time to rework hardware and software for the new design.

	CNETAsia : Printer Friendly - HP set to debut last in-house chip
		Hewlett-Packard is set to debut as soon as next week its first Unix servers with the last member of the company's PA-RISC processor family, a lineage that's being supplanted by Intel's Itanium.
		The PA-8900--like the Alpha EV7z introduced last year--is the final member of an HP chip family the company is phasing out as part of a plan to simplify its high-end server products with Itanium.
		The company is likely to announce June 1 that the PA-8900 processor has arrived in the HP 9000 line of Unix servers, sources familiar with the plan said.

	OpenBSD/hppa
		Later on, Hewlett-Packard decided to sponsor a Linux port to the PA-RISC family, which actually resulted in some proprietary documentation being released, even though their target was a different class of 9000 machines back then.
		One of the major direct benefits from previous porting efforts (besides the code, of course) was support for HP PA-RISC in GCC and binutils, which allowed quick building of a cross-tools environment for development.
		In addition to the release, full snapshots are made periodically, and work is ongoing to provide better hardware support.

		The Intel partnership was designed so the Itanium family would be widely used, attracting widespread support from software companies and computer makers and not being consigned to the high-end boutique niche that HP's own PA-RISC chip family occupy.
		HP came up with the idea behind Itanium in the 1988 and in the 1990s signed a partnership under which Intel was to build and help design the chip family.
		While HP plans to phase out its own PA-RISC processor line two generations from now, the company's two main rivals--IBM and Sun Microsystems--have their own high-end processor lines and therefore have been insulated against the problems Itanium has had getting to market.

	HP outlines plans for Alpha's retirement
		The company is retiring the chip, along with its PA-RISC processors, with plans to move all its higher-end servers to Intel's 64-bit Itanium family.
		Along with Alpha, which it inherited through its merger with Compaq Computer, and its own PA-RISC family, HP has also said it will retire the Tru64 Unix operating system, another Compaq leftover, and merge its best capabilities with its own HP-UX software.
		After that, by around mid-2004, HP will put the Alpha family into "maintenance mode," he said, meaning HP won't develop further versions of the chip.

		The performance of the new processor family is key for HP in particular as the company places most of its eggs in the Itanium basket.
		By contrast, HP will not only adopt Itanium family chips into its machines that compete against Sun and IBM boxes, the company will also eventually insert the chip into the superhigh-end NonStop machines that it acquired in the Compaq Computer merger.
		Flash Communications Server MX, a new addition to the MX family of Web development and server products Macromedia has built this year, is meant to further encourage Web developers to add chat, interactive video and other communications features to their sites, said Kevin Lynch, chief software architect for Macromedia, according to reports published online.

		o The PA8900 is slated for release in the first half of 2003, and will probably be the final processor in the PA-RISC family.
		(Thanks to Cary Coutant, HP) HP will gradually transition its servers from PA-RISC to the new Itanium[TM] processor family (IPF), also known as IA-64, starting in mid 2001.
		At introduction in 1986, it was known as HP's Precision Architecture, HP-PA, or just PA. Subsequently, the architecture was called PA-RISC, with the first version of the architecture known as PA-RISC 1.0.
