x86 assembly opcode table

What is opcode table in assembler?
An opcode table (also called an opcode matrix) is a visual representation of all opcodes in an instruction set.
It is arranged such that each axis of the table represents an upper or lower nibble, which combined form the full byte of the opcode.
mov — Move (Opcodes: 88, 89, 8A, 8B, 8C, 8E, ) The mov instruction copies the data item referred to by its second operand (i.e. register contents, memory contents, or a constant value) into the location referred to by its first operand (i.e. a register or memory)._{8 mar. 2022}

What is the x86 assembly code?

x86 assembly language is the name for the family of assembly languages which provide some level of backward compatibility with CPUs back to the Intel 8008 microprocessor, which was launched in April 1972.
It is used to produce object code for the x86 class of processors.

What is the size of x86-64 opcode?

An x86-64 instruction may be at most 15 bytes in length.
It consists of the following components in the given order, where the prefixes are at the least-significant (lowest) address in memory: Legacy prefixes (1-4 bytes, optional) Opcode with prefixes (1-4 bytes, required)_{8 juil. 2023}
