Ans. The instruction set of 8086 can be divided into the following number of groups, namely: ○. Data transfer instructions. ○. Arithmetic instructions. String is series of bytes or series of words stored in sequential memory locations. The 8086 provides some instructions which handle string operations such as The MOV instruction copies a word or byte of data from a specified source to a specified destination. The destination can be a register or a memory location Converting Assembly Language Instructions to Machine Code. • An instruction can be coded with 1 to 6 bytes. • Byte 1 contains three kinds of information.Microprocessor - 8086 Instruction Sets · Data Transfer Instructions · Arithmetic Instructions · Bit Manipulation Instructions · String Instructions · Program Rotate operand1 left through Carry Flag. The number of rotates is set by operand2. When immediate is greater then 1, assembler generates several RCL xx, 1 The 8086 includes four 16-bit data registers (AX,. BX, CX and DX). These register can be used in arith- metic or logic operations and as temporary storage. The Complete 8086 instruction set.
