  2. Active State Power Management - Wikipedia

    en.wikipedia.org/wiki/Active_State_Power_Management

    Active-state power management (ASPM) is a power management mechanism for PCI Express devices to garner power savings while otherwise in a fully active state. Predominantly, this is achieved through active-state link power management; i.e., the PCI Express serial link is powered down when there is no traffic across it.

  3. PCI Express - Wikipedia

    en.wikipedia.org/wiki/PCI_Express

    PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, Mini PCI-E, mPCIe, and PEM), based on PCI Express, is a replacement for the Mini PCI form factor. It is developed by the PCI-SIG . The host device supports both PCI Express and USB 2.0 connectivity, and each card may use either standard.

    A Mini PCI slot Mini PCI Wi-Fi card Type IIIB PCI-to-MiniPCI converter Type III MiniPCI and MiniPCI Express cards in comparison Mini PCI was added to PCI version 2.2 for use in laptops and some routers; [ citation needed ] it uses a 32-bit, 33 MHz bus with powered connections (3.3 V only; 5 V is limited to 100 mA) and support for bus mastering ...

  5. PCI configuration space - Wikipedia

    en.wikipedia.org/wiki/PCI_configuration_space

    One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...

  6. 16-pin 12VHPWR connector - Wikipedia

    en.wikipedia.org/wiki/16-Pin_12vHPWR_connector

    The 16-pin 12VHPWR connector is a standard for connecting graphics processing units (GPUs) to computer power supplies for up to 600 W power delivery. It was introduced in 2022 to supersede the previous 6- and 8-pin power connectors for GPUs. The primary aim was to cater to the increasing power requirements of high-performance GPUs.

  7. Bus (computing) - Wikipedia

    en.wikipedia.org/wiki/Bus_(computing)

    Four PCI Express bus card slots (from top to second from bottom: ×4, ×16, ×1 and ×16), compared to a 32-bit conventional PCI bus card slot (very bottom). In computer architecture, a bus [1] (historically also called data highway [2] or databus) is a communication system that transfers data between components inside a computer, or between computers.

  8. Message Signaled Interrupts - Wikipedia

    en.wikipedia.org/wiki/Message_Signaled_Interrupts

    PCI Express does not have physical interrupt pins, but emulates the 4 physical interrupt pins of PCI via dedicated PCI Express Messages such as Assert_INTA and Deassert_INTC. Being message-based (at the PCI Express layer), this mechanism provides some, but not all, of the advantages of the PCI layer MSI mechanism: the 4 virtual pins per device ...

  9. ACPI - Wikipedia

    en.wikipedia.org/wiki/ACPI

    Advanced Configuration and Power Interface (ACPI) is an open standard that operating systems can use to discover and configure computer hardware components, to perform power management (e.g. putting unused hardware components to sleep), auto configuration (e.g. Plug and Play and hot swapping), and status monitoring.
