- What is the name of the Intel technology that allows a processor to handle two threads at the same time?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?Why are spinlocks used as a synchronisation method only on multiprocessor systems and not on single processor systems like Solaris, Linux, and Windows 2000?
- The reason why spinlocks are exclusively used as a synchronization mechanism on multiprocessor systems, and not on single-processor systems, is not entirely clear.When it comes to a processor's access to main memory, the loosely connected setup and the symmetric multiprocessing configuration are similar. Explain why, in the real world, the symmetric design might be better.Suppose that you were to design an advanced computer architecture that did process switching in hardware, instead of having interrupts. What information would the CPU need? Describe how the hardware process switching might work.
- The most efficient CPU-to-memory bus is either synchronous or asynchronous. Thanks. Share how you came to this conclusion.When it comes to how a processor can access main memory, the loosely connected setup and the symmetric multiprocessing configuration are similar. In real life, why might the symmetric design be better?There is symmetric multiprocessing, and there is also asymmetric multiprocessing. What are the advantages and disadvantages of using a number of different processors at the same time?
