The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture.
IA-32 (short for "Intel Architecture, 32-bit", commonly called i386 [1] [2]) [3] is the 32-bit version of the x86 instruction set architecture, designed by Intel and first implemented in the 80386 microprocessor in 1985.
i386 first 32-bit x86 processor. Introduced paging on top of segmentation which is the most commonly used memory protection technology in modern operating systems ever since. Many additional powerful and valuable new instructions. i486
The updated instruction set is grouped according to architecture (i186, i286, i386, i486, i586/i686) and is referred to as (32-bit) x86 and (64-bit) x86-64 (also known as AMD64). Original 8086/8088 instructions
x86 (also known as 80x86 [3] or the 8086 family [4]) is a family of complex instruction set computer (CISC) instruction set architectures [a] initially developed by Intel, based on the 8086 microprocessor and its 8-bit-external-bus variant, the 8088.
In computing, Physical Address Extension (PAE), sometimes referred to as Page Address Extension, [1] is a memory management feature for the x86 architecture. PAE was first introduced by Intel in the Pentium Pro, and later by AMD in the Athlon processor. [2]
System Management Mode (SMM, sometimes called ring −2 in reference to protection rings) [1] [2] is an operating mode of x86 central processor units (CPUs) in which all normal execution, including the operating system, is suspended.
In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands.The flags SF, ZF, PF are modified while the numerical result of the AND is discarded. . The OF and CF flags are set to 0, while AF flag is undefin
