Handling Multiple Devices
Interrupt Priority
Controlling device requests
KEN, DEN
Implementation of interrupt priory by using individual interrupt-request and acknowledge lines
Polled interrupts: Priority decided by the order in which processor polls the component (polls their status registers) vectored interrupts: Priority determined by the order in which processor tells component toput its code on the address lines (order of connection in the chain)
(a) Daisy chain
Daisy chaining of INTA: If device has not requested any service, passes the INTA signal to next device if necessitate service, does not pass the INTA, puts its code on the address lines Polled

Takes care structural and behavioural aspect of a software system. Contains software usage, functionality, performance, economic, reuse, and technology constraints.
A interrupt that can be turned off by the programmer is called as Maskable interrupt.
Determine how Simulation can be developed To determine how a simulation can be developed for use in a real situation the below illustration has been chosen. Scenario chosen is
Write short notes on Event Model.
First, remember that different processes keep their own data in distinct address spaces. Threads, on the other hand, explicitly share their entire address space with one another. A
