Why Interrupts Are Not Appropriate For Implementing Synchronization? Answer: Spinlocks are not appropriate for single-processor systems because the condition that would break a process out of the spinlock can be obtained only by executing a different process. Are interrupts appropriate to be used for implementing synchronization primitives? On a multiprocessor system, multiple threads can actually
Can An ISR Be Interrupted? Normally, an interrupt service routine proceeds until it is complete without being interrupted itself in most of the systems. However, If we have a larger system, where several devices may interrupt the microprocessor, a priority problem may arise. What happens to interrupt in ISR? An interrupt is a signal to
How Are Interrupts Handled In 8086? Hardware interrupt is caused by any peripheral device by sending a signal through a specified pin to the microprocessor. The 8086 has two hardware interrupt pins, i.e. NMI and INTR. NMI is a non-maskable interrupt and INTR is a maskable interrupt having lower priority. How does a microprocessor handle
