1 Feb 2016 8086 INSTRUCTION FORMATS Compiled by: L. Krishnananda, Assistant Professor, REVA ITM, Bangalore 3 normally contain the displacement value of a memory operand and / or the actual value of an immediate constant operand. Obtain the opcodes for the following instructions. Example 1 : Code for
The 8086 instruction sizes vary from one to six bytes. Depending on the type of coding, an instruction may have more than one hex code. Figure below shows the instruction format of 8086:

Encoding of 8086 Instructions ! 8086 Instructions are represented as binary numbers. Instructions require between 1 and 6 bytes. Note that some architectures have fixed length instructions. (particularly RISC architectures) byte. 7 6 5 4 3 2 1 0. 1 opcode. d w Opcode byte. 2 mod reg r/m. Addressing mode byte. 3. [optional].
Instruction Format of 8086. The instructions in The immediate byte may be 8 or 16 bit, and the displacement in an instruction can be 0 bits or 8 bits or 16 bits. The OP CODE and Example: MOV CX, [BX], indirect addressing and based-indexed addressing mode without displacement are in this category. Case-2, One byte
Instruction formats of 8086 : The instruction format of 8086 has one or more number of fields associated with it. The first filled is called operation code field or opcode field, which indicates the type of operation. The instruction format also contains other fields known as operand fields.
Real time means the task required by the application must be completed before any other input to the program that will alter its operation can occur. For example the device service routine which controls the operation of the floppy disk drive is a good example that is usually written in assembly language
Example for default segments. • The following registers are used as offsets. Assuming that the default segment used to get the logical address, give the segment register associated? a) BP b)DI c)IP d)SI, e)SP, f) BX. • Show the contents of the related memory locations after the execution of this instruction. MOV [BP][SI]+10,DX.
