What is the difference between IA64 and x64?

What is the difference between IA64 and x64?

IA64 – or Intel Itanium – processors run 64-bit natively and offer 32-bit emulation, but you cannot install 32-bit Windows on it. x64 is the term Microsoft uses to collectively refer to processors that run both 32- and 64-bit code natively without emulation – both AMD64 and EM64T.

What are some of the features of the IA 64 Itanium architecture?

It is a 64-bit register-rich explicitly parallel architecture. The base data word is 64 bits, byte-addressable. The logical address space is 264 bytes. The architecture implements predication, speculation, and branch prediction.

What is Intel Itanium used for?

Itanium was a processor architecture intended for use in servers and high-performance computing.

Is IA 64 dead?

Xeons Will Eventually Replace Itanium With no more new Itanium processors in the pipeline, it looks like the family of IA-64 is dead. With HP set to support Itanium systems until 2025, this will be the last hurrah as the company stocks up for the end.

What kind of instruction set does Itanium 64 have?

IA-64 (also called Intel Itanium architecture) is the instruction set architecture (ISA) of the Itanium family of 64-bit Intel microprocessors. The basic ISA specification originated at Hewlett-Packard (HP), and was evolved and then implemented in a new processor microarchitecture by Intel with HP’s continued partnership…

When did the first Itanium processor come out?

The first Itanium processor, codenamed Merced, was released in 2001. The Itanium architecture is based on explicit instruction-level parallelism, in which the compiler decides which instructions to execute in parallel.

What’s the history of the IA-64 instruction set?

History 1 Development: 1989–2000. In 1989, HP began to become concerned that reduced instruction set computing (RISC) architectures were approaching a processing limit at one instruction per cycle. 2 Itanium (Merced): 2001. 3 Itanium 9700 (Kittson): 2017. 4 End of life: 2021.

When did Intel join the Itanium Solutions Alliance?

In November 2005, the major Itanium server manufacturers joined with Intel and a number of software vendors to form the Itanium Solutions Alliance to promote the architecture and accelerate software porting.
