IA-32. 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. IA-32 is the first incarnation of x86 that supports 32-bit computing; [4] as a result, the "IA-32" term may be used ...
Oct 8, 2019 · IA-32 is ISA on which market of high-end computing, including personal computers, laptops, workstation, and servers, had grown up at the last three decades. This ISA, along with IBM PC architecture, was one of the main drivers of the personal computer revolution and still is one of the principal ISA on the microprocessor market.

Mod=10, same as Mod 01 with 32-bit displacement Mod=11 – Second operand is also a register, numbered by R/M. CS 365 8 Do not confuse displacement width with data width. – Data width is specified by the opcode. – For example, the use of disp8 does not imply 8-bit data. For some opcodes, the reg# is used as an extension of the opcode.
