Older 32-bit drivers and services are not supported by 64-bit Windows, but video and audio codecs such as XviD or OggDS, which are in fact 32-bit DLLs, are supported as long as the media player that uses them is 32-bit as well. Windows XP 圆4 Edition includes both 32- and 64-bit versions of Internet Explorer, in order to allow for the possibility that some third-party browser plugins or ActiveX controls may not yet be available in 64-bit versions. This may lead to the need for library developers to provide both 32- and 64-bit binary versions of their libraries. A 64-bit application cannot link against a 32-bit library (DLL) and similarly a 32-bit application cannot link against a 64-bit library.

As a result, AMD64 microprocessors suffer no performance loss when executing 32-bit Windows applications, whereas IA-64 implementations experience noticeable performance loss.Īlthough 32-bit applications can be run transparently, the mixing of the two types of code within the same process is not allowed.

However, on the IA-64 architecture, WOW64 was required to translate 32-bit x86 instructions into their 64-bit IA-64 equivalents which in some cases were implemented in quite different ways so that the processor could execute them. Since the AMD64 architecture includes hardware-level support for 32-bit instructions, WOW64 simply switches the process between 32- and 64-bit modes. It was first employed in Windows XP 64-bit Edition, but then reused for the “圆4 Editions” of Windows XP and Windows Server 2003. Windows XP 圆4 Edition uses a technology named WOW64, which permits the execution of 32-bit x86 applications.

2 Compatibility with other applications.

1 Compatibility with 32-bit applications.

They both are commonly referred to as 64-bit Windows by Microsoft due to their similarities from the developers' point of view. The 圆4 Edition is not to be confused with the “64-bit Edition”, as the latter was designed for IA-64 (Intel Itanium) processors. In practice, most motherboards compatible with 64-bit processors do not support nearly the maximum, and often retain the 4 GB limit. Microsoft claims this limit will be increased as hardware capabilities improve. Windows XP 圆4 can support much more memory although the theoretical memory limit a 64-bit computer can address is about 18 billion GB (18 exabytes), Windows XP 圆4 is currently limited to 128 GB ( bytes) of physical memory and 16 TB ( bytes) of virtual memory. Windows XP 32-bit is limited to a total of 4 GB, which is equally divided between Kernel and application usage. The primary benefit of moving to 64-bit is the increase in the maximum allocatable system memory (RAM). It is designed to use the expanded 64-bit memory address space provided by the AMD64 architecture Intel refers to its implementation of the technology as EM64T. 1830) as that was the latest version of Microsoft Windows during the operating system's development, but takes Windows XP as its name.

Windows XP Professional 圆4 Edition is based upon Windows Server 2003 SP1 (build.

Microsoft Windows XP Professional 圆4 Edition released on Apby Microsoft is a variation of the typical 32-bit Windows XP operating system for x86 personal computers. For 64-bit Windows for Itanium systems, see Windows XP 64-bit Edition.
