- 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?How does pipelining improve CPU efficiency? What’s the potential effect on pipelining’s efficiency when executing a conditional BRANCH instruction? What techniques can be used to make pipelining more efficient when executing conditional BRANCH instructions?When an operation is stopped and accepted by the CPU, it goes on to the next job, a CPU interrupt is sent. Why can't the process be halted if it's already running? The execution and cleanup can wait till we've resolved the problem, so why not start now?
- When an interrupt occurs, the CPU pauses what it is doing and returns to work on serving the next process. Is a postponement of the execution required? Instead, how about simply carrying out the operation and leaving the rest to us?when a CPU interrupt is sent, the operation is stopped and is acknowledged, the CPU switches to handling the new one. Why shouldn't the process be stopped when it is executing? Instead of dealing with the problem after the fact, why can't we just finish the execution and cleanup?As soon as an interrupt is received, the CPU suspends the process that is presently running and continues to serve the interrupted process. Justification for suspending an already-running procedure As an alternative, why can't we just complete the currently running process and deal with the interrupt afterwards?
- An interrupt is received and the CPU suspends the presently running process in order to deal with it. This is known as interrupt service. What is the reason for suspending the currently running process? As an alternative, why can't we just complete the currently running process and deal with the interruption afterwards?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.whenever an interrupt is triggered, the CPU stops what it is doing and then gets back to work on servicing the next process Is it necessary to postpone the execution? Instead, how about just executing the procedure and taking care of the remainder?
- As soon as an interrupt is received, the CPU suspends the currently executing process and proceeds to service the interrupt. Why should the executing process be suspended? Why can’t we, instead, finish the executing process and handle the interrupt afterward?When a CPU interrupt occurs, the process is stopped and acknowledged, and the CPU moves on to the next one.Why shouldn't the process be stopped while it's still in progress?Why can't we just finish the execution and clean up instead of dealing with the problem after the fact?
