What is the x86 architecture family of the Intel?

instruction set architectures
x86 is a family of instruction set architectures (ISA) for computer processors initially developed by Intel. They refer to the way a computer processor (CPU) handles information. What is an instruction set architecture? It is an abstract model of a computer that is also referred to as computer architecture.

What is Intel x86 family?

x86 is a family of instruction set architectures initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant.

Is x86 a bad architecture?

> x86 is a lousy architecture, but x86-64 isn’t as bad; at least it has a good number of registers unlike x86. You’re still using the 32-128 physical registers on the core. That’s why x86_64 code isn’t particularly faster (sometimes slower) than the same code compiled for x86_32 mode.

How is the Intel x86 architecture has evolved?

Intel x86 architecture has evolved over the years. From a 29, 000 transistors microprocessor 8086 that was the first introduced to a quad core Intel core 2 which contains 820 million transistors, the organization and technology has changed dramatically. Some of the highlights of evolution of x86 architecture are:

Which is the instruction set architecture of Intel 64?

The IA-32 is the instruction set architecture (ISA) of Intel’s most successful line of 32-bit processors, and the Intel 64 ISA is its extension into 64-bit processors. (Actually Intel 64 was invented by AMD, who called it x86-64). These notes summarize a few items of interest about these two ISAs.

What was the name of the first Intel microarchitecture?

Enhanced Pentium M: updated, dual core version of the Pentium M microarchitecture used in the first Intel Core microprocessors, first x86 to have shadow register architecture and speed step technology. commonly referred to as P7 although its internal name was P68 (P7 was used for Itanium ).

Who are the companies that use the x86 architecture?

The architecture has been implemented in processors from Intel, Cyrix, AMD, VIA Technologies and many other companies; there are also open implementations, such as the Zet SoC platform (currently inactive).
