What is Hyper Threading

Explain what is meant by the Hyper Threading? Specify some of its use.




A thread of the execution, or simply a thread, is one of the series of instructions that are sent to the CPU. Hyper-threading is defined as a technology that is designed to help make better use of the spare processing cycles. Hyper-threaded processors have the duplicate set of registers, small spaces of the high-speed memory storage used to hold data that is presently required to execute the thread. When CPU core is delayed, waiting for the data to get retrieved from other place in the memory, it may use these duplicate registers to spend the spare computation cycles executing the several threads. Second set of the registers will be pre-loaded along with the data required to execute second thread, thus the CPU core may begin work immediately.
