- If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?What happens to the CPU when a software requests input/output (I/O)? How is it communicated to the CPU when the IO operation is complete?The CPU suspends its present operation upon receiving a signal in order to reply to the request. How the mechanism operates: A' Interrupt signal Spooling with B' Interrupt handling C' Polling
- What happens to the CPU when a software makes a request for input/output (/0)? What mechanism is used to inform the CPU that the 10 operation has been completed?As soon as an interrupt occurs, the CPU suspends the current process. This is interrupt service. Why is the present procedure suspended? Why not simply finish the present task and deal with the interruption later?As soon as an interrupt occurs, the CPU suspends the current process and deals with the interruption. Interrupt service is the technical term for this. Why is the current procedure being halted? How about we just complete this process and deal with the interruption afterward?
- So, what happens to the CPU when a software requests input/output? What is the technique that is utilised to inform the CPU that the 1O has been completed successfully?When a signal is received, the CPU suspends its current activity to respond to the request. Here's how the mechanism works: A' Signal to interrupt Spooling with B C' Handling of interrupts D Polling.When an interrupt occurs, the CPU suspends the current process to handle it. It's called interrupt service. Why is the present procedure being suspended? Why can't we simply finish the present task and deal with the interruption later?
- When an interrupt occurs, the CPU suspends the current process to deal with the problem.Interrupt service is the term for this.What is the justification for halting the current procedure?Instead, why don't we just complete the current procedure and deal with the interruption later?What does it mean to "interrupt" someone? What kinds of interruptions are there? What causes interruptions? When an interrupt occurs, how does the CPU handle it?When an interrupt is received, the CPU immediately suspends the current process and begins responding to the interrupt. Is there a good reason to stop a running process? Because finishing the process of executing it and dealing with interrupts are mutually exclusive.
