The clock generation circuit includes an edge detection circuit, a reference clock generation circuit, a reference clock counter circuit, and a frequency-divider circuit. The reference clock counter circuit is a circuit which outputs a counter value, which is obtained by counting the number of waves of a reference clock signal outputted from the reference clock generation circuit, in a period of time from when the edge detection circuit detects an edge of a signal which is externally inputted to the edge detection circuit to when the edge detection circuit detects the next edge, to the frequency-divider circuit. The frequency-divider circuit is a circuit which frequency-divides the reference clock signal based on the counter value.

Abstract: A communication channel includes a first component having a transmitter coupled to a normal signal source, and a second component having a receiver coupled to a normal signal destination. A communication link couples the first and second components. Calibration logic provides for setting an operation value for a parameter of the communication channel, such as by executing an exhaustive calibration sequence at initialization of the link. A tracking circuit, including a monitoring function, tracks drift in the parameter by monitoring a feedback signal that has a characteristic that correlates with drift in the communication channel, and updates, or indicates the need for updating of, the operation value of the parameter in response to the monitoring function.

Abstract: A UEFI compliant firmware is disclosed that includes a UEFI legacy boot loader. The UEFI legacy boot loader provides functionality for loading operating systems that are non-UEFI compliant in a performant manner. In particular, the UEFI legacy boot loader provided in one embodiment disclosed herein is configured to utilize UEFI disk services to load an O/S kernel and other O/S components. Once the UEFI legacy boot loader has completed loading the O/S components, the UEFI legacy boot loader enables interrupt handling by the O/S, relocates O/S real mode kernel setup code to a low memory region (below 1 MB), and switches a processor to a real mode of operation. The UEFI legacy boot loader then causes the real mode kernel setup code to be executed on the processor, to thereby complete the loading of the operating system.

Abstract: Systems and methods are disclosed for limiting power consumption of a non-volatile memory (NVM) using a power limiting scheme that distributes a number of concurrent NVM operations over time. This provides a “current consumption cap” that fixes an upper limit of current consumption for the NVM, thereby eliminating peak power events. In one embodiment, power consumption of a NVM can be limited by receiving data suitable for use as a factor in adjusting a current threshold from at least one of a plurality of system sources. The current threshold can be less than a peak current capable of being consumed by the NVM and can be adjusted based on the received data. A power limiting scheme can be used that limits the number of concurrent NVM operations performed so that a cumulative current consumption of the NVM does not exceed the adjusted current threshold.

Abstract: Usage data monitored at information handling systems is collected and analyzed to provide a basis for component selection for information handling systems by associating components with end user usage profiles. For example, a monitor tracks usage data at an end user information handling system and determines that the end user's usage falls within usage pattern defined by analysis of plural other end users. The end user is directed towards selection of components associate with the defined usage pattern to replace components of the information handling system or for use in a replacement information handling system. Analysis on an enterprise-wide basis helps an enterprise to allocate components and information handling systems to end users of an enterprise.

Abstract: An interface card is capable of communicating with an external device and includes a power supplier; a non-volatile memory which stores executable instructions to operate in an active-mode and a sleep-mode; a small-capacity volatile memory which is supplied with power in the sleep mode; a transmitter-receiver which transmits and receives packet data to/from the external device; and a controller which retrieves sleep-mode instructions stored in the non-volatile memory and loads the sleep mode instructions in the small-capacity volatile memory to transition the interface card into the sleep mode if the transmitter-receiver does not receive the packet data for predetermined time period in an active mode. The interface card processes certain packet data in the sleep mode and transitions back into the active mode when sleep mode operations determine that the packet data cannot be processed in the sleep mode.
