NettetWhen there are two operands, both operands must have the same size (except shift and rotate instructions). For example: AL, DL DX, AX m1 DB ? AL, m1 m2 DW ? AX, m2 Some instructions allow several operand combinations. For example: memory, immediate REG, immediate memory, REG REG, SREG NettetImmediate operands and operands in registers can be accessed more rapidly than operands in memory since memory operands must be fetched from memory. Register …
