- _____ is a CPU design technique in which instruction execution is divided into multiple stages and different instructions can execute in different stages simultaneously.A(n) ________________ instruction always alters the instruction execution sequence. A(n) ______________ instruction alters the instruction execution sequence only if a specified Condition is true.Processor R is a 64-bit RISC processor with a 2 GHz clock rate. The average instruction requires one cycle to complete, assuming zero wait state memory accesses. Processor C is a CISC processor with a 1.8 GHz clock rate. The average simple instruction requires one cycle to complete, assuming zero wait state memory accesses. The average complex instruction requires two cycles to complete, assuming zero wait state memory accesses. Processor R can’t directly implement the complex processing instructions of Processor C. Executing an equivalent set of simple instructions requires an average of three cycles to complete, assuming zero wait state memory accesses. Program S contains nothing but simple instructions. Program C executes 70% simple instructions and 30% complex instructions. Which processor will execute program S more quickly? Which processor will execute program C more quickly? At what percentage of complex instructions will the performance of the two processors be equal?
- 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 a CPU interrupt occurs, the processor comes to a halt and responds to the signal. Why should the process be halted so that this duty may be completed? Let's start with the pausing procedure and then go on to the carrying out process. explain?When a CPU interrupt occurs, the processor stops its current operation and reacts to the signal. Why should the operation be halted so that this may be performed? Let's begin with the process of cessation and then proceed to the procedure of execution. Explain?
- An interrupt from a CPU causes the processor to halt what it is doing and react to the signal received from the interrupt source. In order to finish this work, why should the operation be stopped? Let's start with the process of interrupting, and then go on to the process of executing the interrupting. explain?When a computer processor has many instructions running at once, how can it prevent wasting computation cycles that it would otherwise utilise if it were only carrying out one instruction? It should be indicated what occurred as a direct result of what they did in the previous phrase.When a computer is driven by hardwire, the microgram defines the instructions for the user. This instruction set can not be modified until the design is overhauled. What is the significance of Positive or Negative in this situation?
