Intel Architecture is a system of processor architectures developed by Intel . These architectures were compatible only with their own set of instructions and one of them was used in processors of other companies. It is currently divided into two architectures: IA-32 and IA-64 .

IA-32
IA-32 ( Intel Architecture, 32-bit ) - microprocessor architecture , the third generation of x86 architecture, marked by the transition to 32-bit computing [1] [2] [3] . The first representative of the architecture is the Intel 80386 microprocessor , released on October 17, 1985 . Also, the architecture is often called i386 (by the name of the first processor released on it) and x86-32 (by the applicable set of commands). These metonyms are widely used, including in reference books and documentation [4] [5] .
The IA-32 architecture, created by Intel in 1985, has dominated microprocessors for personal computers for twenty years [2] . Later it was supplanted by the x86-64 64-bit architecture [6] .
Processors with IA-32 architecture were also manufactured by AMD , Cyrix , Via , Transmeta , SiS , UMC and many others [1] . After 2010, IA-32 architecture processors are still being developed and manufactured, for example, Intel Atom (N2xx and Z5xx series) [7] , AMD Geode and VIA C7 ? which are positioned as processors for mobile and embedded systems.
IA-64
- not to be confused with x86-64
IA-64 ( Intel Architecture-64 ) - 64-bit hardware platform : microprocessor architecture and related instruction set architecture , developed jointly by Intel and Hewlett Packard . It is implemented in Itanium and Itanium 2 microprocessors.
It is based on VLIW or, in terms of Intel, EPIC (abbr. From English Explicity Parallel Instruction Computing , calculations with explicit parallelism of instructions). Incompatible with x86 architecture. Initially it was offered as a platform for home computers, but after AMD released the 64-bit AMD64 architecture , which retained x86 compatibility, the relevance of using the IA-64 platform elsewhere, except for servers, disappeared, despite the fact that at the end of 2001 a special version of Windows XP 64-bit for IA-64 was released for IA-64. Also, the OpenVMS operating system, owned by HP, has been ported to the IA-64 architecture.
