WebThe High Precision Event Timer (HPET) hardware follows a specification by Intel and Microsoft, revision 1. Each HPET has one fixed-rate counter (at 10+ MHz, hence “High Precision”) and up to 32 comparators. WebThe High Precision Event Timer (HPET) hardware follows a specification by Intel and Microsoft, revision 1. Each HPET has one fixed-rate counter (at 10+ MHz, hence “High Precision”) and up to 32 comparators. Normally three or more comparators are provided, each of which can generate oneshot interrupts and at least one of which has additional ...

The High Precision Event Timer (HPET) is a hardware timer available in modern x86-compatible personal computers. Compared to older types of timers available in the x86 architecture, HPET allows more efficient processing of highly timing-sensitive applications, such as multimedia playback and OS task switching. … See more An HPET chip consists of a 64-bit up-counter (main counter) counting at a frequency of at least 10 MHz, and a set of (at least three, up to 256) comparators. These comparators are 32- or 64-bit-wide. The HPET is … See more The HPET can produce periodic interrupts at a much higher resolution than the RTC and is often used to synchronize multimedia streams, … See more Operating systems designed before HPET existed cannot use HPET, so they use other timer facilities. Newer operating systems tend to be able to use either. Some hardware has both. Indeed, most current southbridge chips have legacy-supporting … See more HPET is meant to supplement and replace the 8254 programmable interval timer and the RTC's periodic interrupt function. Compared to these older timer circuits, the HPET has higher frequency and wider 64-bit counters (although they can be driven in 32-bit mode). See more HPET is a continuously running timer that counts upward, not a one-shot device that counts down to zero, causes one interrupt and then stops. Since HPET compares the actual timer value … See more Web• Event Timer • HPET • MM Timer • MMT The terms Timer, Event Timer, HPET, MMT and MM Timer refer to the combination of e Comparator compares the contents of the Match Register against the value of a free running up-counter. When the output of the up-counter equals the value in the match register an interrupt is generated. The IA-PC WebThe High Precise Event Timer (HPET) is enabled in Unified Extensible Firmware Interface (UEFI) by default. In some specific environments, users need to disable the HPET in their configuration. For instructions on how to enable or disable the HPET option, refer to the Solution section.
