| | X86 - Wikipedia, the free encyclopedia |
 | | The x86 architecture first appeared inside the Intel 8086 CPU in 1978; the 8086 was a development of the 8008 processor (which itself followed the 4004). | | | x86 or 80x86 is the generic name of a microprocessor architecture first developed and manufactured by Intel. | | | The x86 architecture is a CISC design with variable instruction length. |

| | Most likely, the outdated aspects of the x86 instruction set will end up emulated either in processor microcode or by the operating system at some point. | | | While it was considered at one point RISC chips would inevitably replace the outdated and quirky x86 architecture, in fact AMD64 effectively turns x86 into a modern RISC type programming environment. | | | It is used by 64 bit Operating Systems; among those that support Long Mode are Linux, the various BSDs, Solaris 10, MenuetOS and Windows XP Professional x64 Edition. |

| | IA-64 - definition of IA-64 in Encyclopedia |
| | Unlike previous Intel x86 processors, the Itanium is not geared toward high performance execution of the IA-32 (x86) instruction set. | | | In a mainstream "out-of-order" design, a complex decoder system examines each instruction as they flow through the pipeline and sees which can be fed off to operate in parallel across the available execution units — e.g. | | | Even for this usage, it remains doubtful that IA64 will ever be a commercial success, because 64bit extensions to the x86 architecture are gaining ground in server systems (see below). |

| | This may be the first time that Intel has choosen to reverse-engineer an AMD technology, since Intel generally prefers to develop new technologies on its own. | | | It seems you councel that we should not be paying attention to what x86 processor is best for what task, but that all x86 processors are the same and to get the best performance for an application we should be looking at what architecture performs best. | | | Anywho, x86 is quickly monopolizing the entire range of computer markets, and may well eventually take over, but I doubt it. |

Note that this article deals with the x86-64 ISA only. | | | Also, don't take the instruction and code "sizes" too literally, since they're intended to convey a general feel for what it means to "widen" a processor from 32 bits to 64 bits.

| | LinuxQuestions.org - AMD64 (x86_64) and Flash - where Linux users come for help |
| | I ended up getting mplayerplug-in working by using the dag yum package repository and doing a yum install mplayer.i386 (I used the i386 version of the dag repository instead of x86_64) and that installed 32 bit mplayer and all the 32 bit libraries it depended on, except one, libxmms. | | | I ended up switching to the 32 bit version of firefox, then just the automatic flash installer worked fine. | | | However, I also wanted mplayerplug-in so I could watch realvideo, realaudio, quicktime, wmv, microsoft streams; it turns out if you compile mplayer for 64 bit linux it does not support the win32 codecs (necessary for a lot of quicktime/real/microsoft formats); I couldn't figure out how to compile a 32 bit mplayer on 64 bit fedora. |

| | AMD ships Linux 64-bit Hammer x86-64 simulator The Register |
| | AMD has released its Linux-based 'Hammer Sim' - a simulator that allows developers to run and debug code written for Chimpzilla's upcoming x86-64 64-bit processor technology. | | | - available free from AMD's Web site - lets coders test their software on a regular 32-bit x86 CPU. | | | AMD's Hammer family of chips, the successors to Sledgehammer, will be unveiled in full at the end of 2001. |

| | Higher levels of integer precision require more structures to deal with the additional digits, and therefore more complexity, size, power usage, and generally expense. | | | The simpler microcontrollers are usually cheaper, use less power, and therefore dissipate less heat, all of which can be major design considerations for electronic devices. | | | It is not at all uncommon, therefore, to see 4 or 8 bit microcontrollers used in modern applications, even though CPUs with much higher precision (such as 16, 32, 64, even 128 bit) are available. |

| | Slashdot NetBSD Ported to AMD x86-64 (Sledgehammer) |
| | Transmeta, which has a soft architecture, ought to be able to convert their code morpher to process the AMD 64-bit instruction set, which is basically x86 with longer words. | | | This would be useful mostly as a test environment until AMD gets the real machine out the door. |
