Understanding the Purpose of Interrupt Vector Table in a Microprocessor System

In a microprocessor system, the Interrupt Vector Table plays a crucial role in managing and prioritizing interrupts. The Interrupt Vector Table contains a list of memory addresses, each corresponding to a specific interrupt service routine. When an interrupt is triggered, the microprocessor looks up the corresponding memory address in the Interrupt Vector Table to determine the appropriate action to take.

Interrupts are essential for handling events that require immediate attention, such as hardware signals or time-sensitive tasks. By utilizing the Interrupt Vector Table, the microprocessor can efficiently navigate and respond to various interrupt requests. This mechanism helps optimize the system's performance by ensuring prompt and organized handling of interrupts, ultimately enhancing the overall functionality and reliability of the microprocessor system.

Overall, the Interrupt Vector Table serves as a crucial resource for managing interrupts effectively in a microprocessor system, enabling seamless execution of tasks and facilitating swift responses to external events.
