Computer Architecture And Design Interview Question:

Can you explain the two hardware methods to establish priority?

Submitted by: Administrator

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.
