Everything about Opcode prefix

Part of a computer instruction

In computing, an opcode prefix is a numeric prefix code that alters the function of a following opcode. On some instruction set architectures multiple opcode prefixes are allowed sequentially, with all combining to alter the subsequent opcode. The opcode prefix is a portion of a larger machine language instruction that specifies the operation to be performed. Wikipedia →
