摘要： Techniques are described for using geographic location data of snowplows to update a snow depth associated with a section of a surface street. The route of the snowplow may be tracked continuously which allows the snow depth of the street to be reset in real-time. The updated snow depth may then be used to generate a cost of travelling on the street. The travelling cost may then be used to plan a route through the region. Alternatively, the cost may be graphically displayed on a map to permit a user to determine which surface streets to avoid. In another embodiment, the cost of travelling on a particular street may be changed by the attributes of the vehicle that will navigate the snow-covered roads, driver's experience, or the geographic terrain of a road. This new cost may then be used, for example, to plan a route or display roads to avoid.

摘要： An apparatus and method for evaluating a state of an electronic or integrated circuit (IC), each IC including one or more processor elements for controlling operations of IC sub-units, and each the IC supporting multiple frequency clock domains. The method comprises: generating a synchronized set of enable signals in correspondence with one or more IC sub-units for starting operation of one or more IC sub-units according to a determined timing configuration; counting, in response to one signal of the synchronized set of enable signals, a number of main processor IC clock cycles; and, upon attaining a desired clock cycle number, generating a stop signal for each unique frequency clock domain to synchronously stop a functional clock for each respective frequency clock domain; and, upon synchronously stopping all on-chip functional clocks on all frequency clock domains in a deterministic fashion, scanning out data values at a desired IC chip state. The apparatus and methodology enables construction of a cycle-by-cycle view of any part of the state of a running IC chip, using a combination of on-chip circuitry and software.

摘要： In an embodiment, if a self thread has more than one conflict, a transaction of the self thread is aborted and restarted. If the self thread has only one conflict and an enemy thread of the self thread has more than one conflict, the transaction of the self thread is committed. If the self thread only conflicts with the enemy thread and the enemy thread only conflicts with the self thread and the self thread has a key that has a higher priority than a key of the enemy thread, the transaction of the self thread is committed. If the self thread only conflicts with the enemy thread, the enemy thread only conflicts with the self thread, and the self thread has a key that has a lower priority than the key of the enemy thread, the transaction of the self thread is aborted.
