High Precision Event Timer
Under High Precision Event Timer (HPET) is defined as a high-precision timers in modern computers.
This timer is able to trigger interrupts with a very high temporal resolution (quantization) . This enables programs to better synchronize a series of parallel actions such as data streams. Various multimedia applications can work more effectively with HPET.
Until the application and use of HPET, this task was done by the real-time clock and a timer in the interrupt controller.
