Which instruction in 8086 microprocessor is 6 bytes long?
mov
What is the MOV instruction of microcontroller PIC16F877A?
•The mov instruction carries out assignment in 8086 assembly language. •It which allows us place a number in a register or in a memory location (a variable) i.e. it assigns a value to a register or variable. Example: Store the ASCII code for the letter A in register bx.•A has ASCII code 65D (01000001B, 41H) •The following mov instruction carries out the task:•mov bx, 65d•We could also write it as:•mov bx, 41h•or mov bx, 01000001b•or mov bx, 'A'
Why mov R1R2 is invalid instruction?
mov r1r2 is invalid instruction because of there is no communication with ALU in its operation;
What is the size of the instruction queue in 8086?
In 8086 the instruction queue is 6 byte long. This is because even the longest 8086 instruction is 6 byte long. Thus it is possible to prefetch even the longest instruction in the instruction set.
What is immediate addressing of register?
i.e.-->mov ax,2000h (in 8086)
Specify the opcode and operand in the instruction MOV HL?
