'''HPET''', or High Precision Event Timer, is a piece of hardware designed by Intel and Microsoft to replace older [[PIT]] and [[RTC]]. It consists of (usually 64-bit) main counter (which counts up), as well as from 3 to 32 32 or 64 bit wide comparators. HPET is programmed using memory mapped IO, and the base address of HPET can be found using [[ACPI]].▼
