Web21.3. Instruction Naming Instruction mnemonics are suffixed with one character modifiers which specify the size of operands. The letters b, w, l and q specify byte, word, long and quadruple word operands. If no suffix is specified by an instruction then as tries to fill in the missing suffix based on the destination register operand (the last one by convention). WebThe IDIV (signed divide) instruction performs signed integer division, using the same operands as the DIV instruction.. For both DIV and IDIV, all of the arithmetic status flags are undefined after the operation. When doing 8-bit division, you must sign-extend the dividend into AH before using IDIV.. For example, (-48/5): .DATA byte_val SBYTE -48 … Webthat scale defaults to 1). Most instructions (e.g., mov) permit at most one operand to be a memory value. Instructions are byte-aligned, with a variable number of bytes. The size of an instruction depends mostly on the complexity of its addressing mode.
