Expert Solution
Step 1
Interrupt Vector Table:
- The Interrupt Vector Table (IVT) is a data structure used by computers and microcontrollers to handle interrupts, which are signals that indicate an event or condition that requires the attention of the processor.
- The IVT is a table of memory locations that contain addresses of the interrupt service routines (ISRs), which are programs that handle the interrupts. Each entry in the IVT is associated with a specific interrupt number, and the processor uses the IVT to determine which ISR to execute when a particular interrupt occurs.
- When an interrupt is generated, the processor looks up the corresponding entry in the IVT, retrieves the address of the ISR, and jumps to that address to execute the ISR. Once the ISR is completed, the processor returns to the main program and resumes its normal execution.
