Non Maskable Interrupt: The hardware which cannot be delayed and should process by the processor immediately. A) i- True, ii- False, iii-True B) i- False, ii- True interrupts are enabled, when they were previously disabled a MIPS instruction is executed As a result, unlike real hardware, interrupts (including time-slice context switches) cannot occur just anywhere in the code where interrupts are enabled, but rather only at those places in the code where simulated time advances (so that it becomes time for the hardware simulation to invoke an interrupt handler). The interrupting device gives the address of sub-routine for these interrupts. Nested interrupts are allowed if later interrupt is higher priority than previous one. • External interrupts are routed from peripherals to CPUs in multi processor systems through APIC • APIC distributes and prioritizes interrupts to processors • Interrupts can be configured as edge or level triggered • Comprises of two components – Local APIC (LAPIC) – I/O APIC • APICs communicate through a special 3-wire APIC bus.

The IRR is used to store all the interrupt levels which are requesting service; and the ISR is used to store all the interrupt 1 poll is cheaper than 1 interrupt; but 1 interrupt guarantees an event, polling may have thousands of wasted polls. When a microprocessor is executing a main program and whenever an interrupt occurs, the microprocessor shifts the control from the main program to process the incoming request. These are different than internal interrupts that happen automatically as the machine reads through program instructions. They are. Interrupt ‘bounce’ values may defined differently for each mapped external interrupt, as necessary, to reflect the ‘cleanliness’ of the triggering circuitry. When a process exceeds its time limit, the timer interrupts that process and puts it in suspended processes. This bit must be set to one to enable these I/O devices to generate an interrupt when the Ready bit comes true. The data transfer can be either in two forms namely parallel or serial respectively.

Feedback: 1. )Business owners should focus on telling customers how the features of their products are different from other available products. The appropriate use of interrupts is absolutely essential to achieving effective use of MCUs. Microprocessor responds to these interrupts with an interrupt service routine (ISR), which is a short program or subroutine to instruct the microprocessor on how to handle the interrupt. Which of the following statements regarding hyperopia is NOT true? A)It is also called farsightedness. A CPU supports 4 interrupts- I1, I2, I3 and I4. In 8086 microprocessor one of the following statements is not true. A maskable interrupt can be in two states: masked or unmasked; a masked interrupt is ignored by the control unit as long as it remains masked. All Interrupt Requests (IRQs) issued by I/O devices give rise to maskable interrupts. Similarly, there is the TimerThree library for generating interrupts on Timer3 (not applicable for Arduino Uno). iii i,iv ii,iii iii,iv. i) It controls the degree of multi-programming ii) It determines which programs are admitted to the system for processing. The 8085 checks for an interrupt during the execution of every instruction. A Boolean value that, if TRUE, indicates that the system will save the processor's floating point and MMX state when the device interrupts.

If the signal handler returns, the calling process resumes execution immediately following the point at which it received the interrupt signal. A. For non-SysTick interrupts, in addition to enabling interrupts in the peripherals IMR, we need to write to the the NVIC (Nested Vector Interrupt Controller) and indicate that we want to enable an interrupt from a given peripheral.
