    摘要: Method and apparatus for metering network services, for example Web services. In embodiments, a network services metering system may collect network service usage information via an add usage interface and store the usage information in a database. In one embodiment, the usage information may be partitioned into two or more partitions. Once the usage information has been aggregated and stored, the metering system may be queried to obtain usage statistics such as aggregate usage over specific time intervals. In one embodiment, a pipeline mechanism that generates and processes batches of usage information may be implemented for adding usage information to the database. The pipeline mechanism may help to reduce or eliminate redundancy and loss of usage information, and may make the metering system linearly scalable in multiple dimensions.

    摘要: A method and apparatus for automatically securing non-volatile (NV) storage in an integrated circuit provides improved resistance to code copying and reverse-engineering attacks. External interfaces that provide read access to the NV storage are be disabled, for a predetermined time after a reset or other initialization signal is received. An internal lock state bit or key is checked as well as an external lock prevent indication. If the lock prevent indication is not received, or the internal lock state bit is already set, then the integrated circuit is operated under a locked condition, in which external access to the NV storage values is prevented. The lock prevent indication may be a signal provided during reset of the integrated circuit on a terminal that is used for another purpose after initialization of the integrated circuit.

    摘要: A system in which drooping of the video levels due to leakage currents and proper DC bias level is addressed by providing a charge into the video signal to offset the leakage currents and to provide DC bias. To determine the leakage current level, measurements are made measuring the voltages of the syncs and the blanking intervals. To determine the DC bias, a measurement is made of the sync. Over a series of video lines these measurements are averaged. If the average is below the desired level, a charge is provided via a current source to the incoming signal. By having the current source provide charge during each video line, droop is reduced and the proper DC bias is provided.
