Abstract: A method for long impulse response digital filtering of an input data stream, by use of a digital filtering system. Where the input data stream is divided into zero-input signals and zero-state signals. One of the zero-input signals and a corresponding impulse response of the digital filtering system is converted lo the frequency domain to determine a respective zero-input response of the digital filtering system. One of the zero-state signals is convolved with a corresponding impulse response of the digital filtering system to determine a respective zero-state response of the digital filtering system, wherein at least part of the zero-input signal precedes the zero-stale signal. The zero-state response of the digital filtering system is added to the zero-input response or the digital filtering system to determine the response of the digital filtering system. Apparatus for effecting this method is also disclosed.

Abstract: A method of programming cells in a nonvolatile memory is based upon a Global Verify operation and a Byte-by-byte Verify operation. The cells of a destination page of the nonvolatile memory are programmed, and logic values stored in the programmed cells of a source page of the same memory are verified that they have been correctly copied into corresponding cells of the destination page. The method carries out the fast but inadequate-at-times Global Verify operation, and if the Global Verify operation fails for a certain number of attempts, the Byte-by-byte Verify operation is carried out, which is slower but accurate.

Abstract: An address counter for a nonvolatile memory device includes a cascade of cells. Each cell includes an address counting flip-flop that is updated to a value of every newly counted address bit, or latches a column address bit value input by an external user of the memory device during ALE cycles for addressing a start memory location on a selected page. Each cell further includes an additional address loading flip-flop for loading the column address bit value input during ALE cycles for addressing the start memory location on the selected page during the ALE cycles. A logic circuit updates the address counting flip flop to the address bit value during a read confirm cycle in a read sequence, and during a first data input cycle in a program sequence.

Abstract: A Yule-Walker based, low-complexity voice activity detector (VAD) is disclosed. An input signal is typically noisy speech (i.e., corrupted with, for example, babble noise). In one embodiment, a first initialization stage of the VAD computes an occurrence of a silent period within the input signal and the AR parameters. The VAD could accordingly compute a tentative adaptive threshold and output hypothesis H1 (which means speech is present) during this stage. During the second initialization stage, the VAD generally builds a database of associated values and computes the adaptive threshold accordingly. The second initialization stage could also output tentative VAD decisions based on the tentative threshold computed in the first initialization stage. Finally, the VAD periodically retrains or updates AR parameters, threshold values and/or the database and outputs VAD decisions accordingly.

Abstract: The electrical isolation circuit of the present disclosure includes a switch coupled between the DC power source and the electrical application and a comparator for controlling the switch by receiving inputs from the DC power source and the electrical application. The comparator causes the switch to switch ON when the DC power source has a higher voltage than the electrical application allowing the normal operation of the electrical application. However, when the electrical application has a higher voltage than the DC power source, the comparator causes the switch to switch OFF thereby preventing flow of current from the electrical application to the DC power source.

Abstract: A method for stereo audio perceptual encoding of an input signal includes masking threshold estimation and bit allocation. The masking threshold estimation and bit allocation are performed once every two encoding processes. Another method for stereo audio perceptual encoding of an input signal includes performing a time-to-frequency transformation, performing a quantization, performing a bitstream formatting to produce an output stream, and performing a psychoacoustics analysis. The psychoacoustics analysis includes masking threshold estimation on a first of every two successive frames of the input signal.

Abstract: A method for adaptive pre-filtering is disclosed, comprising the steps of: extracting tuning parameters from video encoding process; processing these tuning parameters to generate control parameters representative of the properties of the video data processed; coupling the control parameters to filter response; generating filter coefficients on selected filter response; and filtering the video data with the filter coefficients before video encoding. The filtering of video data is thus adapted to at least one or more tuning parameters of the video data and the encoding process. The filtering decreases the complexity of encoding by attenuation of high frequency, effectively decreasing the quantization step and reducing compression artifacts.
