It encounters the HLT instruction when there is not an endless loop or other things that are done endlessly.
HLT
All the programming instructions whcih are basically in the assembly code has the corresponding hexadecimal code.the microprocessor understand or interprets what this code is and based on that it performs operation for eg HLT which had hexcode 76 the microprocessor understands76 as tha halt instruction and based on that it halts or terminates the program Anand bhat(mca@kiit-870024)
It fetches the next instruction.
branch instruction
it goes to queue for next instruction
Special restart instruction used with interrupts
it has an instruction set of a few hundred instructions.
The Instruction Pointer (IP) in an 8086 microprocessor contains the address of the next instruction to be executed. The processor uses IP to request memory data from the Bus Interface Unit, and then increments it by the size of the instruction.
A=HL+A or A=DE+A
1byte instruction = MOV A,B 2byte instruction = MVI A,01H 3byte instruction = STA 2030H
Yes.
