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.
An excellent paper explaining almost all practical aspects for a transition from 32-bit to 64-bit. Intel 64 Architecture; Intel Software Network: "64 bits" TurboIRC.COM tutorials, including examples of how to of enter protected and long mode the raw way from DOS; Seven Steps of Migrating a Program to a 64-bit System; Memory Limits for Windows ...
Intel oneAPI DPC++/C++ Compiler is available for Windows and Linux and supports compiling C, C++, SYCL, and Data Parallel C++ (DPC++) source, targeting Intel IA-32, Intel 64 (aka x86-64), Core, Xeon, and Xeon Scalable processors, as well as GPUs including Intel Processor Graphics Gen9 and above, Intel X e architecture, and Intel Programmable Acceleration Card with Intel Arria 10 GX FPGA.

Itanium never sold well outside enterprise servers and high-performance computing systems, and the architecture was ultimately supplanted by competitor AMD's x86-64 (also called AMD64) architecture. x86-64 is a compatible extension to the 32-bit x86 architecture, implemented by, for example, Intel's own Xeon line and AMD's Opteron line.
Rocket Lake: Successor to Comet Lake, using Intel's 14++ nm process, released on March 30, 2021 [14] [15] [16] Willow Cove Successor to the Sunny Cove core, includes new security features and redesigns the cache subsystem. [17] Tiger Lake: successor to Ice Lake, using Intel's 10 nm SuperFin (10SF) process, released in Q4 2020; Golden Cove
The compilers generate code for IA-32 and Intel 64 processors and certain non-Intel but compatible processors, such as certain AMD processors. A specific release of the compiler (11.1) remains available for development of Linux-based applications for IA-64 processors. On Windows, it is known as Intel Visual Fortran. [2]
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors , from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model .
It is intended as an extensible architecture; the first accelerator implemented is called tile matrix multiply unit (TMUL). [5] [6] In Intel Architecture Instruction Set Extensions and Future Features revision 46, published in September 2022, a new AMX-FP16 extension was documented. This extension adds support for half-precision floating-point ...
