  2. ACPI - Wikipedia

    en.wikipedia.org/wiki/ACPI

    All ACPI-conformant processors must support this power state. Some processors, such as the Pentium 4 and AMD Athlon, also support an Enhanced C1 state (C1E or Enhanced Halt State) for lower power consumption, however this proved to be buggy on some systems. [38] [39]

    AMD K6-2 – an improved K6 with the addition of the 3DNow! SIMD instructions. AMD K6-III Sharptooth – a further improved K6 with three levels of cache – 64 KB L1, 256 KB full-speed on-die L2, and a variable (up to 2 MB) L3. AMD K7 Athlon – microarchitecture of the AMD Athlon classic and Athlon XP microprocessors. Was a very advanced ...

  5. Dynamic frequency scaling - Wikipedia

    en.wikipedia.org/wiki/Dynamic_frequency_scaling

    ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...

  6. Power management - Wikipedia

    en.wikipedia.org/wiki/Power_management

    Power management is a feature of some electrical appliances, especially copiers, computers, computer CPUs, computer GPUs and computer peripherals such as monitors and printers, that turns off the power or switches the system to a low-power state when inactive.

  7. Embedded controller - Wikipedia

    en.wikipedia.org/wiki/Embedded_controller

    SCI from the Embedded Controller to inform the ACPI driver (in the OS) of an ACPI Event; As a core system component, the embedded controller is always on when power is supplied to the mainboard. To communicate with the main computer system, several forms of communication can be used, including ACPI, SMBus, or shared memory.

  8. Zen 4 - Wikipedia

    en.wikipedia.org/wiki/Zen_4

    Zen 4 is the first AMD microarchitecture to support AVX-512 instruction set extension. Most 512-bit vector instructions are split in two and executed by the 256-bit SIMD execution units internally. The two halves execute in parallel on a pair of execution units and are still tracked as a single micro-OP (except for stores), which means the ...

  9. KolibriOS - Wikipedia

    en.wikipedia.org/wiki/KolibriOS

    There are two development branches: KolibriACPI, which has extended ACPI support, and Kolibri-A, an exokernel version of KolibriOS optimized for embedded applications and hardware engineering; only few AMD APU-based platforms are currently supported.
