In order to implement polling, the hardware has to be able to prioritize and encode multiple interrupt signals before alerting the processor. O True False An array of function pointers, each of which refers to a handler, is a simple, hardware-supported data structure called a... stack O IVT O linked list interrupt service table call graph Which of the following components of an event-based interrupt scheme is a signal? ISR O handler IRO O All of the above. O None of the above. When we say an interrupt is "pending," it means that ... the processor is currently in debug mode. the hardware device (peripheral) is not ready to generate an interrupt. the interrupt handler has not yet completed the processing of the interrupt. the hardware has been informed that interrupt has been recognized. the processor is blocked until the next rising clock edge. The most significant bit in the two-byte value OxA5 is ... O O O 1
