MicroProcessor AnD InterfacinG -
MicroProcessor:-
def:-A MicroProcessor is a multipurpose,programmable,clock-driven,register-based electronic device that reads binary instructions from a storage device called memory,accepts binary data as input and processes the data according to those instruction,and provides results as output.
MP Unit5
Interrupts
Interrupts
Def:- An interrupt operation suspends
execution of a program so that the system can take special action.The
interrupt routine executes and normally returns control to the interrupted procedure, which then resumes execution.BIOS handles Int 00H-1FH, whereas DOS handles INT 20H-3FH.
