Physical Address=(Segment Address×10H)+Offset AddressPhysical Address equals open paren Segment Address cross 10 cap H close paren plus Offset Address
Uses a base or index register plus an optional displacement. 4. Instruction Set Categories Data Transfer: MOV , PUSH , POP , XCHG , IN , OUT . Arithmetic: ADD , SUB , INC , DEC , MUL , DIV . Logical: AND , OR , NOT , XOR , SHL , SHR . Branch/String: JMP , CALL , RET , LOOP , MOVS , CMPS . 5. Memory Segmentation
Below is a structured "solid paper" overview for this subject, focusing on the core concepts (specifically the 8086 microprocessor) often required for model answers and exams. 1. Introduction to 8086 Microprocessor
Data is part of the instruction (e.g., MOV AX, 0005H ).
Decodes and executes instructions using the Arithmetic Logic Unit (ALU), flags, and general-purpose registers. 2. Architecture and Register Organization
