Can You Explain The Two Hardware Methods To Establish Priority?
Two different ways of establishing hardware priority are Daisy Chaining and parallel priority. Daisy chaining is a form of a hardware implementation of the polling procedure. Parallel priority is quicker of the two and uses a priority encoder to establish priorities. In parallel priority interrupt a register is used for which the bits are separated by the interrupt signals from every device. The parallel priority interrupt may also contain a mask register which is primarily used to control the status of every request regarding interrupts.
