HPET - OSDev Wiki
ウェブ2023年7月10日 · 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-bit or 64-bit wide comparators. HPET is programmed using memory mapped IO, and the base address of HPET can …
ウェブHigh Precision Event Timer (HPET) 6.2.2 Timer Off-load. The PCH supports a timer off-load feature that allows the HPET timers to remain operational during very low power S0 operational modes when the 24-MHz clock is disabled. The clock source during this off-load is the Real Time Clock’s 32.768-KHz clock.
