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 ...
The PCIe Physical Layer (PHY, PCIEPHY, PCI Express PHY, or PCIe PHY) specification is divided into two sub-layers, corresponding to electrical and logical specifications. The logical sublayer is sometimes further divided into a MAC sublayer and a PCS, although this division is not formally part of the PCIe specification.
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.
Although discs scratched by the Xbox 360 are not covered under its warranty, [40] Microsoft's Xbox Disc Replacement Program [41] will sell customers a new copy of discs scratched by the Xbox 360, if they are published in countries where the Xbox was originally sold, at a cost of $20. [42] The published list of games that qualify, however, is ...
Performance lies between a Geforce 3 Series GPU and a Geforce 4 Series GPU. This is due to the added vertex shader present on the ASIC, thus doubling the vertex output compared to Geforce 3 ASICs. Clock speed is the same as the original Geforce 3 series GPU (233MHz) thus slower than Geforce 4 series starting at 250MHz.
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.
The projected result was a 5–15% failure rate within three years of 3 Gbit/s SATA ports, commonly used for storage devices such as hard drives and optical drives. The bug was present in revision B2 of the chipsets, and was fixed with B3. Z68 did not have this bug, since the B2 revision for it was never released. 6 Gbit/s ports were not affected.
Platform Environment Control Interface (PECI) is an Intel proprietary single wire serial interface that provides a communication channel between Intel processors and chipset components to external system management logic and thermal monitoring devices.
