摘要： The Advanced Encryption Standard (AES) cipher can be performed in a manner that preserves the secrecy of cryptographic keys, even under the intense scrutiny of a reverse-engineer observing every aspect of the computation. A method can include loading a key in a non-standard representation. The method can also include processing the key with respect to data in at least three first type rounds and a plurality of second type rounds. The processing the key with respect to data can include either encrypting the data using the key or decrypting the data using the key. The first type rounds can be configured to maintain an order of channels of bits at an output from the order of corresponding channels of bits at an input. The second type rounds can be configured to vary the order of channels of bits at an output from the order of corresponding channels of bits at an input.

摘要： An efficient and flexible current-mode driver delivers power to one or more light sources in a backlight system. In one application, the current-mode driver (306, 308) is configured as an inverter with an input current regulator, a non-resonant polarity-switching network, and a closely-coupled output transformer. The input current regulator can output a regulated current source in a variety of programmable wave shapes. The current-mode driver may further include a rectifier circuit (320, 322, 324, 326) and a second polarity-switching network between the closely-coupled output transformer (310) and a lamp load (312). In another application, the current-mode driver delivers power to a plurality of light sources in substantially one polarity by providing a regulated current to a network of time-sharing semiconductor switches coupled in series with different light sources coupled across each semiconductor switch.

摘要： A merged PN/Schottky diode is provided having a substrate of a first conductivity type and a grid of doped wells of the second conductivity type embedded in the substrate. A Schottky barrier metal layer makes a Schottky barrier contact with the surface of the substrate above the grid. Selected embedded wells in the grid may contact the Schottky barrier metal layer, while most embedded wells do not. The diode forward voltage drop is reduced for the same diode area with reverse blocking benefits similar to a conventional JBS structure.
