Answer / Rishi Kant Pal
The steps involved in a fetch cycle for an 8086 microprocessor are:
1. Fetch Opcode: The processor fetches the opcode (operation code) of the next instruction from memory.
2. Decode Opcode: The processor decodes the opcode to determine the operation to be performed and other necessary information such as the size and destination of operands.
3. Fetch Operand(s): If the instruction requires an operand, the processor fetches it/them from memory based on the information gathered during opcode decoding.
4. Execute: The processor executes the operation specified by the opcode using the operands fetched.
