- 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?Find the ratio of CPU utilization for a system spend 120 minutes to execute the processes and the total latency (Context switch time) time is 20 minutes.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 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?
