Explain the two hardware methods to establish priority - Computer architecture and design
Briefly 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.
