    摘要: A semiconductor package contains at least one electrically isolated channel. The isolated channel is minimally susceptible to crosstalk from other channels in the package. Specifically, the level of crosstalk that may impinge on the isolated channel is below an acceptable threshold so as to permit the isolated channel to function correctly. The semiconductor package may be a FET switch assembly and the isolated channel may be used for a clock signal to prevent crosstalk contamination caused by the data signals.

    摘要: An electronic system includes a fan and a fan controller connected to the fan to control a speed of the fan. The fan controller has storage locations for storing thermal data used by the fan controller to control the speed of the fan. A thermal sensor generates a first portion of the thermal data, which is readable by the fan controller, and which the fan controller stores in a first portion of the storage locations. A device generates a second portion of the thermal data, which is not readable by the fan controller. An agent writes the second portion of the thermal data to a second portion of the storage locations.

    摘要: A remote management controller may include a capture engine and a processor. The capture engine may be configured to: obtain a slice of video data output from a video graphics controller; calculate at least one value correlative to the slice of video data; determine whether any portion of the slice has been locked; and if any portion has not been locked and if the calculated value for such portion of the slice differs from a value for a previously obtained corresponding portion, move the portion to a virtual screen buffer, update a table associated with the virtual screen buffer with the calculated value, and modify a change table to indicate that the portion has changed. The processor may be configured to: read the change table to determine whether any portion of video data in the virtual screen buffer has changed; and if any portion has changed, lock any changed portion from being accessed by the capture engine, access the changed portion from the virtual screen buffer, and process the changed portion in the virtual screen buffer for transmission to a remote system.

    摘要: A hot spare boot circuit that automatically switches from a non-operational CPU to an operational CPU for powering up the computer system. In the multiprocessor computer system, a first CPU is designated to perform power on operations. If the first CPU fails, which is determined when a dead man counter in the hot spare boot circuit times out, the hot spare circuit ensures that the first CPU is in a disabled state. Next, the hot spare boot circuit identifies an operational second CPU, reinitializing certain ID information as necessary such that the second CPU can properly perform power on operations. The hot spare boot then awakens the second CPU, using a startup interprocessor interrupt in one embodiment, or simply negating the hard reset of the second CPU in a second embodiment. The second CPU then proceeds to perform the power on functions.
