Interrupts are not sufficient in multiprocessor systems since disabling inter rupts only
prevents other processes from executing on the processor in which inter rupts were disabled; there are
no limitations on what processes could be executing on other processors and therefore the process
disabling interrupts cannot guarantee mutually exclusive access to program state.
Because they are completely unrelated things? Synchronization can be implemented with semaphores or mutexes.
There are three types of interrupts.... 1. internal Interrupts 2. External Interrupts 3. Software Interrupts... read more
it has 256 interrupts ..
An interrupt is an event that alters the sequence in which the processor execute instructions. It is generated by hardware of computer system. Classes of interrupt:- IBM processor has six types of interrupts. * svc interrupt(supervisor call) *input/output interrupts *external interrupts *Restart interrupts *Program check interrupt *Machine check interrupts
1.The excluding interrupts are INT0 & INT1 2.The Timer0 and Timer1 are interrupts are generated by TF0 and TF1
Maskable interrupts trigger events are not always important and so the programmer can decide that the event should not cause a program to jump. Nonmaskable interrupts can not be ignored by the programmer and therefore they have absolute priority.
Multiple interrupts refers to errors that may occur when a system is operational. The interrupts may be caused by a single error repeatedly or by different errors.
The Enable Interrupts (EI) and Disable Interrupts (DI) instructions allow the MP to permit or deny interrupts under program control.
The likely word is the verb form "interrupts."
Those would be software interrupts. Interrupts initiated by the hardware would be hardware interrupts. While the socket a mouse is plugged into would use a hardware interrupt, a mouse driver would use a software interrupt.
Hardware interrupts can be controlled by the 8259 Programmable Interrupt Controller
The fluctuation in the power surges is an example of the types of interrupts in a microprocessor.
