  • Publication number: 20120001679
    Abstract: An embodiment of an electrically trimmable electronic device, wherein a resistor of electrically modifiable material is formed by a first generally strip-shaped portion and by a second generally strip-shaped portion, which extend transversely with respect to one another and are in direct electrical contact in a crossing area. The first and second portions have respective ends connected to own contact regions, coupled to a current pulse source and are made of the same material or of the same composition of materials starting from a same resistive layer of the material having electrically modifiable resistivity, for example, a phase-change material, such as a Ge—Sb—Te alloy, or polycrystalline silicon, or a metal material used for thin-film resistors. The trimming is performed by supplying a trimming current to the second portion so as to heat the crossing area and modify the resistivity thereof, without flowing longitudinally in the first portion.

    Abstract: A circuit base cell is for implementing an engineering change order (ECO) obtained on a semiconductor substrate. The base cell may include a PMOS transistor having a first active region obtained in a first diffusion P+ layer implanted in an N-well provided for on the substrate, and an NMOS transistor having a second active region obtained in a second diffusion N+ layer implanted on the substrate in such a manner as to be electrically insulated from the first diffusion P+ layer. The cell may be characterized in that the active regions and the diffusion layers are aligned therebetween with respect to a reference axis and they are extended symmetrically in the direction orthogonal to the axis. A first and a second width may be associated with the active regions and to the diffusion layers, respectively. The first and second width may be greater than a width of the cell, which is equivalent to a pitch of the standard minimum cell.

  • Publication number: 20110320209
    Abstract: A multiband dynamics compressor implements a frequency-domain solution for addressing unwanted magnitude peaks which may occur at the crossover frequency (boundary) between two adjacent frequency bands. The solution proposes making slight adjustments to the frequency band boundary locations, for example on a frame-by-frame basis, in order to prevent a spectral peak in the input signal from being located midway between two frequency bands. The adjustment to the boundary location pushes the energy of the spectral peak substantially into one frequency band for compression.

  • Publication number: 20110320916
    Abstract: A method is for generating, for each check node related to a parity check equation of a LDPC code, signals representing a first output table of corrected values of symbols of a word received through a communication channel and transmitted according to the LDPC code, and signals representing a second output table of the logarithm of the ratio between the respective probability of correctness of the values of same coordinates in the first output table and their corresponding maximum probability of correctness. The method is implemented by processing the components of a first input table of values of a Galois Field of symbols that may have been transmitted and of a second input table of corresponding probability of correctness of each value.

  • Publication number: 20110316812
    Abstract: A device has a variable function or operation. An image sensor system is provided for the device. The image sensor system is responsive to light rays indicative of whether an object is present on an imaging window. For example, the image sensor system may be of the frustrated total internal reflection type, the light rays detected by the image sensor system comprising reflected light from the window at locations where the object is not present. The image sensor system outputs image information indicative of the detection of the light rays. A processing circuit processes the image information to detect the presence of the object on the imaging window. A control signal is generated by the processing circuit in response to that detected presence, the control signal causing the variable function or operation of the device to vary in response to the detected presence and/or movement of the object.

  • Publication number: 20110320210
    Abstract: A multiband dynamics compressor implements a solution for minimizing unwanted changes to the long-term frequency response. The solution essentially proposes undoing the multiband compression in a controlled manner using much slower smoothing times. In this regard, the compensation provided acts more like an equalizer than a compressor. What is applied is a very slowly time-varying, frequency-dependent post-gain (make-up gain) that attempts to restore the smoothed long-term level of each compressor band.

  • Publication number: 20110320795
    Abstract: An embodiment of a method and system are provided for managing both system resources and power consumption of a computer system, involving different layers of the system: an application layer, a middle layer where the operating system is running and where a power manager is provided, and a hardware layer used for communicating with the hardware devices. Hardware devices have different operating modes which provide distinct trade-offs between performances and power consumption. Performance requirements defined at the level of the application layer, as well as the device power status of the system, set constraints on the system resources. The middle layer power manager may be in charge of retrieving performance requirements in form of constraints set on system parameters, aggregating these constraints opportunely and communicating corresponding information to the device drivers which may then select a best operating mode.
