摘要： As one embodiment a drive circuit is disclosed. When a three-value signal including a value representing zero is input, the drive circuit outputs two two-value signals that drive two drive elements such that the difference between values representing the two two-value signals corresponds to a value representing the input three-value signal. When the value of the input three-value signal represents zero, output signals are determined in accordance with the input history of the three-value signal. The drive circuit may also be provided with a memory that records a flag value that is reversed in accordance with the input history of the input three-value signal, and the combination of the output two two-value signals being determined in accordance with the flag.

摘要： Disclosed are a method and device for data compression, transmission, and decompression. In the present method, data-to-be-transmitted is grouped by a transmitting terminal, and for each group: a shift factor is determined based on the most significant bit of sample data of the greatest value in the group when a sign bit is removed, data bits of the sample data in the group are left shifted by the shift factor; the left shifted sample data respectively are quantified, thus making the bit number of the quantified sample data to be equal to a predefined bit number; the shift factor and the quantified sample data are transmitted to a receiving terminal. Employment of the present application optimizes data compression performance.

摘要： The present disclosure includes methods and apparatuses for mapping between program states and data patterns. One method includes: programming a group of G memory cells such that a combination of respective program states of the group maps to a constellation point corresponding to a received N unit data pattern, the group used to store N/G units of data per memory cell; wherein the constellation point is one of a number of constellation points of a constellation associated with mapping respective program state combinations of the group of memory cells to N unit data patterns; and wherein the constellation comprises a first mapping shell and a second mapping shell, the constellation points corresponding to the respective first and second mapping shells determined, at least partially, based on a polynomial expression of order equal to G.

摘要： An encoder encodes data to generate corresponding encoded data. The encoder includes a data processing arrangement for applying one or more encoding processes to the data to generate the encoded data. The data processing arrangement is operable to represent the data at least partially in a set of numerical value symbols, if the data is not already expressed in numerical value symbols. The data processing arrangement is operable to generate intermediate data in which the numerical value symbols are represented by original values and at least one symbol by a modified value with one or more continuum symbols generated by a continuum operator. The one or more continuum symbols modify preceding symbol values to accommodate an extended range of symbols.
