What is stack in microprocessor?
The stack is a region of memory set aside to store register values and operands.
What do you mean by operators and operands?
operands are the objects or variable that we create in our program. operators fuse with the operands to build a mathematical statement in the program.
How does 8086 differentiate between an opcode and operand?
The 8086 microprocessor differentiates between an opcode and an operand primarily through the instruction format, where the opcode is always specified first, followed by the operands. The opcode indicates the operation to be performed, while the operands represent the data or addresses on which the operation will act. The instruction's length is variable, and the processor uses specific bits in the instruction to determine the types and sizes of operands, allowing it to interpret the instruction correctly. Additionally, the opcode itself can include information about the addressing mode, further aiding in the distinction between opcodes and operands.
What does it mean to find the product of something?
Product means to multiply the operands. The product of 5 and 6 is 30. Sum means to add the operands. The sum of 5 and 6 is 11.
What do you mean by infix?
The operator is between the two operands, like 4+6
What do you mean by 8 bit?
An 8 bit microprocessor is a 'microprocessor' which only has an 8 bit wide databus.
What is compare instruction 8086 microprocessor?
the compare instruction of 808 is used to compare the 2 operands. syntax: cmp op1,op2 algorithm: op1-op2 the value of the operands are not affected only the flags are updated if op1<op2 carry=1 and zero flag=0 if op1=op2 cy=0 and zf=1 if op1>op2 cy=0 and zf=0
What do you mean by tri state condition in a microprocessor?
tristates
What is the advantage of addressing mode in 8086 microprocessor?
The addressing modes in the 8086 microprocessor provide flexibility in accessing data by allowing various ways to specify the operands for instructions. This enables programmers to efficiently use memory by accessing data directly, indirectly, or using offsets, which can simplify code and reduce the number of instructions needed. Additionally, different addressing modes facilitate the manipulation of data structures, such as arrays and records, enhancing the overall versatility and power of the microprocessor.
How is parity flag affected with the or instruction in 8086 microprocessor?
In the 8086 microprocessor, the parity flag (PF) is affected by the OR instruction based on the result of the operation. The parity flag is set if the number of set bits (1s) in the result is even; it is cleared if the number of set bits is odd. Therefore, after executing an OR instruction, the parity flag reflects the parity of the result of the logical OR operation performed on the operands.

What is the maximum length of instruction in 8086?
In the 8086 microprocessor, the maximum length of an instruction is 6 bytes. This includes the opcode, any necessary prefixes, and operands. The architecture allows for complex addressing modes, which can contribute to the instruction length, but the limit remains at 6 bytes for any single instruction.
