X64 - Wikipedia, the free encyclopedia As of December 2005, current implementations of the x64 architecture only implement the low-order 48 bits of virtual addresses, but pointers are nevertheless 64 bits wide and all 64 bits must be correctly asserted. Thus the x64 appellation does not indicate whether the operating system or software is optimally working with one processor or another. Internally, x64 versions of Windows use AMD64 moniker to designate various components which use 64-bit technology for IA-32 processors (for example, the system folder on an installation CD is named "AMD64" instead of "i386" in 32-bit versions). en.wikipedia.org /wiki/X64   (284 words)

White Paper: Benefits of x64 for Audio Workstations The x64 architecture is an extension to the current x86 architecture used by Intel and AMD processors. The x64 architecture extends this limit to 2 40, which is 1024 GB or 1 terabyte (TB). Furthermore, on x64 processors all floating point math is computed using Streaming SIMD Extensions technology (SSE/SSE2), which means the DSP code can exploit parallelism in the data, for example by processing stereo streams in parallel. www.cakewalk.com /x64/whitepaper.asp   (1891 words)

AMD64 - Wikipedia, the free encyclopedia x64 editions of both Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1 were released in March 2005. Internally these are actually the same version and build (version 5.2 build 3790) of Windows: Windows XP SP2 for x64 and Server 2003 SP1 for x64 are built from the same source files and even share many operating system binaries, much in the manner of Windows 2000 Professional and Server editions for x86. Maintaining this convention made the x64 port easier, but required AMD to retain the function of the FS and GS segments in long mode— even though segmented addressing per se is not really used by any modern operating system. en.wikipedia.org /wiki/AMD64   (2135 words)

Paul Thurrott's SuperSite for Windows: Windows XP Professional x64 Edition RC2 Preview XP x64 is still a subset, of sorts, of XP 32-bit, but the missing features in XP x64 were dropped with good reason. But XP x64 is not compatible with the multitudes of 32-bit hardware drivers that are currently available for every single device under the sun. There is little doubt that x64 is the future of desktop computing, but attempting to move to XP x64 will prove to be a fruitless trip for many people. www.winsupersite.com /reviews/windowsxp_x64_preview2.asp   (3353 words)

Paul Thurrott's SuperSite for Windows: Windows XP Professional x64 Edition Mini-Review Back then, XP x64 Edition had just been recast as a first class Windows citizen that would closely follow the feature-set of the mainstream 32-bit version of Windows XP; originally, it was going to be seriously hobbled, offering just a subset of XP Pro's features. As I did with the RC2 version of XP x64 in that second preview, I kept detailed records of my two installs of the final version of XP x64 (first in the spring and the again last week). Today, XP x64 is just like Windows for Workgroups 3.11 was in 1994: It had virtually all of the advanced 32-bit technology Microsoft would later tout in Windows 95, though few people noticed at the time. www.winsupersite.com /reviews/windowsxp_x64.asp   (1299 words)

Windows x64 64-bit introduction x64 is the name of Microsoft's new 64-bit operating systems that allow for 64-bit applications, memory addressing and up to 16 Terabytes of virtual memory space, as well as being backwards compatible with most 32-bit applications (but not drivers). x64 indicates support for 64-bit extended technology and is a shorthand derivative of x86-64, a term commonly used to describe processors that have added 64-bit extensions to the industry-standard x86 instruction set (e.g., AMD Athlon 64, AMD Opteron, Intel Xeon with EM64T and Intel Pentium with EM64T). Windows x64 will be able to run in native mode on all Intel Xeon EM64T 800FSB processors, Intel P4 processors with EM64T (currently 6xx series), the upcoming P4 8xx dual-core series, upcoming P4 5x1 series, upcoming Celeron D 3x1 series, Athlon64’s and Opterons. www.asisupport.com /windows_x64_intro_article.htm   (1956 words)

Paul Thurrott's SuperSite for Windows: Windows Server 2003 x64 Editions Preview The Windows Server 2003 x64 Editions are comprised of Windows Server 2003 Standard x64 Edition and Windows Server 2003 x64 Enterprise Edition, which roughly correspond to the similarly named 32-bit versions of Windows Server 2003. For virtually every server application imaginable, x64 is the platform of the future, and one that all Windows Server administrators should be thinking about and, potentially, evaluating this year. As with XP x64, driver and application compatibility will likely bedevil many users this year, but the by the release of Longhorn Server (expected in early 2007), x64 will be the mainstream server platform. www.winsupersite.com /reviews/win2003x64_preview.asp   (1287 words)

x64 news and notes This means that when you are done using x64, if you dont like it, you must format the drive or partition its on and remove the boot.ini entries for it. Also, x64 editions enforce drive decoration, which means that you might have a 64bit driver but it will appear to fail to install properly. There should be an x64 version of it in the near future. x64news.blogspot.com   (1082 words)

FreiK's WebLog : x64 ABI vs. x86 ABI (aka Calling Conventions for AMD64 & EM64T)   (Site not responding. Last check: 2007-10-21) There is a persistent misconception among people who are implementing x64 compilers/code generators, and folks that write ASM code for x64, who have a functioning solution for x86. With this in mind, on x64 every function has a very strict structure that must be properly described in static data. The x64 Windows ABI is a 4 register ‘fast-call’ calling convention, with stack-backing for those registers. blogs.msdn.com /freik/archive/2005/03/17/398200.aspx   (2465 words)

After a week of using the final version of XP x64, I did notice one major difference when compared with the release candidates: Windows Update now navigates to the Windows Server 2003 Service Pack 1 (SP1) version of Microsoft's Web-based software patch and update service. However, XP x64 includes over 15,000 device drivers, more than any previous Windows version, and many more will be available on Windows Update in the near future. www.pcworld.com /reviews/article/0,aid,120559,00.asp   (365 words)

Registry changes in x64-based versions of Windows Server 2003 and in Windows XP Professional x64 Edition Computers that are running an x64-based version of Microsoft Windows Server 2003 or Microsoft Windows XP Professional x64 Edition use a different registry layout to handle both 32-bit and 64-bit programs. The registry layout changes in x64 Edition versions of the Windows operating system make sure that the programs hard-coded.dll paths, program settings, and other parameter values are not overwritten.

Setup and installation considerations for Windows x64 Edition-based computers The Windows x64 installation process is similar to the installation process for the Windows x86 operating system. The x64 installation still copies the needed files to temporary folders, restarts the computer into graphical user interface (GUI) mode, performs Plug and Play (PnP) detection and installation, and then finishes the set up process. At release the Windows x64 Edition operating system will only be distributed for evaluation or through MSDN, Software Assurance, volume channels and OEM channels. support.microsoft.com /kb/896334   (687 words)

Windows Server Division WebLog : Windows Server 2003 SP1 and X64 Editions - A Historical Perspective Patterson ended the course with a memorable lecture with career advice for his students as they headed out into the “real world.” One thing he said that resonates strongly in my work with x64 was that very few of his students would ever get a chance to work on a new computer architecture. His words proved prophetic in my experience driving the Windows team’s work on x64, a remarkable new architecture that will give every day people unprecedented computer power on their desktops.

Microsoft Stakes Claim to x64 Future Citing the overwhelming popularity of server hardware based on the 64-bit x64 platform, Microsoft yesterday announced an aggressive roadmap for moving its server products off of the 32-bit x86 platform. The beauty of the x64 platform is that it is backwards compatible with the x86 software that is common today. Thus, most 32-bit Windows software will run on x64 systems, and will provide better performance and, of course, access to far greater amounts of system memory. www.windowsitpro.com /windowspaulthurrott/Article/ArticleID/48464/windowspaulthurrott_48464.html   (810 words)
