Itanium (/ aɪ ˈ t eɪ n i ə m /; eye-TAY-nee-əm) is a discontinued family of 64-bit Intel microprocessors that implement the Intel Itanium architecture (formerly called IA-64). The Itanium architecture originated at Hewlett-Packard (HP), and was later jointly developed by HP and Intel.
IA-64 (Intel Itanium architecture) is the instruction set architecture (ISA) of the discontinued Itanium family of 64-bit Intel microprocessors. The basic ISA specification originated at Hewlett-Packard (HP), and was subsequently implemented by Intel in collaboration with HP. The first Itanium processor, codenamed Merced, was released in 2001.
Itanium 2 uses socket PAC611 with a 128 bit wide FSB.The 90 nm CPUs (9000 and 9100 series) bring dual-core chips and an updated microarchitecture adding multithreading and splitting the L2 cache into a 256 KB data cache and 1 MB instruction cache per core (the pre-9000 series L2 cache being a 256 KB common cache).
original Itanium microarchitecture. Used only in the first Itanium microprocessors. McKinley enhanced microarchitecture used in the first two generations of the Itanium 2 microprocessor. Madison is the 130 nm version. Montecito enhanced McKinley microarchitecture used in the Itanium 2 9000- and 9100-series of processors.
2.16 64-bit processors: Intel 64 – Sandy Bridge / Ivy Bridge microarchitecture. ... Itanium 2 (chronological entry – new non-x86 architecture) Introduced July 2002;
On the Itanium architecture, WoW64 was required to translate 32-bit x86 instructions into their 64-bit Itanium equivalents—which in some cases were implemented in quite different ways—so that the processor could execute them. All 32-bit processes are shown with *32 in the task manager, while 64-bit processes have no extra text present.
The term IA-64 refers to the Itanium processor, and should not be confused with x86-64, as it is a completely different instruction set. Many operating systems and products, especially those that introduced x86-64 support prior to Intel's entry into the market, use the term "AMD64" or "amd64" to refer to both AMD64 and Intel 64. amd64
It was the basis for Intel and HP development of the Intel Itanium architecture, [3] and HP later asserted that "EPIC" was merely an old term for the Itanium architecture. [4] EPIC permits microprocessors to execute software instructions in parallel by using the compiler, rather than complex on-die circuitry, to control parallel instruction ...
