Question: An interrupt-based I/0 system uses polled interrupt handling where the processor has to interrogate each peripheral's interrupt status flag after an interrupt request. Suppose that

An interrupt-based I/0 system uses polled interrupt handling where the processor has to interrogate each peripheral's interrupt status flag after an interrupt request. Suppose that an interrupt request takes 2 µ,s, an interrupt return takes 1.5 µ,s , and it takes 0.5 µ,s to poll a potential interrupter. The interrupt handling routine takes 5 µ,s. If an interrupt must be responded to within 50 µ,s , what is the maximum number of peripherals that can be supported?
