Abstract: In various examples, methods may include receiving first data transmitted from a second component and second data transmitted from the second component during a first time period. The first data may be transmitted via a first data lane and the second data may be transmitted via a second data lane. The method may include receiving de-skew symbols at an interval from the second component via the first data lane and via the second data lane during the first time period. The method may include compensating for a first skew introduced to a first propagation of the first data across the first data lane and a second skew introduced to a second propagation of the second data across the second data lane using the de-skew symbols received during the first time period.

Abstract: In various examples, a diagnostic circuit is connected to a target system to automatically trigger the target system to enter a diagnostic mode. The diagnostic circuit receives diagnostic data from the target system when the target system performs a diagnostic operation in the diagnostic mode.

Abstract: A system, method, and computer program product are provided for utilizing a data pointer table pre-fetcher. In use, an assembly of a data pointer table within a main memory is identified. Additionally, the data pointer table is pre-fetched from the main memory. Further, data is sampled from the pre-fetched data pointer table. Further still, the sampled data is stored within a data pointer table cache.

Abstract: A technique for controlling (e.g. (re)setting, adjusting, fixing, increasing, decreasing, determining, monitoring, calculating, measuring, storing) a holding time of a request from a controller of a host device to an endpoint of a peripheral device across a universal serial bus reduces power and memory loss and enhances overall system performance. The host device may include a programmable and/or hardwired controller for controlling the amount of time before the request from the host device is initially sent and/or resent to the endpoint of the peripheral device across the universal serial bus.

Abstract: A method for command transmission between systems is introduced. The command transmission between the systems, such as a north bridge chip, a south bridge chip and a central processing unit (CPU), employs the signals transmission specified by a PCI Express bus originally for the communication between system chips or peripheral devices. The signals transmission includes an interrupt or a system management instruction specified by the PCI Express bus, which further defines the specific addresses of a memory packet and a system message packet. In the preferred embodiment, the method thereof comprises the steps of transmitting an INTA command first, then a second system chip upstreams an INTR/system-management command to a first system chip. After that, the first system chip downstreams an EOI/system-management command to the second system chip.

Abstract: A computer system and a method of signal transmission via a PCI-Express bus is provided for transmitting a power-saving signal among a plurality of peripheral devices. For the peripheral devices coupled with the system chips can enter a power-saving mode successfully, a signal snooping and blocking manners are introduced into the system chips. The present invention is to improve on a problem that the system chips cannot enter the power-saving mode simultaneously since the system chips don't set any power-management unit therein.

Abstract: A PCI-Express bus is incorporated in a method for transmitting a power-saving command between a computer system and its plurality of peripheral devices of the present invention. More particularly, a specific power management command is introduced into the signal transmission protocol of a system command, which is transmitted between the plural system chips. Therefore, the peripheral devices coupled with the system chips can enter a certain power mode simultaneously. The present invention is used to solve the problem of the peripheral devices cannot enter the certain power mode since the system chip has no power management unit disposed under the PCI-Express structure.

Abstract: A method for transmitting a power-saving command between a computer system and system chips thereof is described. A power-saving command associated with a first system chip is introduced to the computer system since a BIOS is modified therefore. The CPU of the computer system determines the power mode of the first system chip according to a register therein. As the first system chip enters the power-saving mode, the second system chip is informed entering the power-saving mode as well. Therefore, the peripheral devices coupled to the system chips can enter the power-saving mode smoothly so as to solve that the devices cannot enter the mode simultaneously since there is no power management unit (PMU) installed in the first system chip.
