segun wikipedia es :
High Precision Event Timer (
HPET) is a replacement timer for the
8254 Programmable Interval Timer and the
Real-time clock's (RTC) periodic interrupt function. The HPET can produce periodic interrupts at a much higher resolution than the RTC and is often used to synchronize multimedia streams, providing smooth playback and reducing the need to use other timestamp calculations such as an x86 cpu's
RDTSC instruction.
