    • Methods and apparatus for transforming data into a format which may be efficiently stored in a non-volatile memory are disclosed. According to one aspect of the present invention, a method for storing information of a first data format in a memory system includes generating statistics associated with the first data format, and transforming the information from the first data format to a second data format using the statistics. Once the information is transformed into the second data format, the information is stored into a memory. Storing the information in the second data format in the memory includes storing an identifier that identifies a transformation used to transform the information to the second data format. In one embodiment, costs associated with storing the information in the second data format are less than or equal to costs associated with storing the information in the first data format.
    • 公开了将数据转换成可以有效地存储在非易失性存储器中的格式的方法和装置。 根据本发明的一个方面,一种用于将第一数据格式的信息存储在存储器系统中的方法包括生成与第一数据格式相关联的统计信息,以及使用统计信息将信息从第一数据格式转换为第二数据格式 。 一旦信息被转换成第二数据格式,信息被存储到存储器中。 以第二数据格式存储在存储器中的信息包括存储识别用于将信息变换为第二数据格式的变换的标识符。 在一个实施例中,与以第二数据格式存储信息相关联的成本小于或等于与以第一数据格式存储信息相关联的成本。

    • A method of compressing a digital ink input is disclosed. The digital ink includes a sequence of strokes, each stroke being represented as a series of digital words representing x and y co-ordinates, the compressed digital ink data including, for each stroke, at least one reference co-ordinate expressed in absolute terms, with subsequent co-ordinates being expressed in terms of an offset from a co-ordinate, estimated using linear prediction, such that a given co-ordinate may be determined on the basis of the previous m co- ordinates as formula (I); where CI are coefficients dependent on the nature of the digital ink, and alpha represents either an x or a y co-ordinate.
    • 公开了一种压缩数字墨水输入的方法。 数字墨水包括笔画序列,每个笔划被表示为表示x和y坐标的一系列数字单词,压缩的数字墨水数据包括每个笔画至少一个以绝对值表示的参考坐标, 随后的坐标用与使用线性预测估计的坐标的偏移来表示,使得可以基于先前的坐标作为公式(I)确定给定的坐标; 其中CI是取决于数字墨水性质的系数,而alpha表示x或y坐标。

    • PURPOSE: A method and an apparatus for coding/decoding digital data are provided to enhance coding efficiency in a bit division coding process by improving a digital data coding/decoding method. CONSTITUTION: A plurality of samples as components of digital data are mapped onto a bit plane by performing a mapping process. A coding process is performed to code bit-sliced data of the bit plane in orders of the bit-sliced data for the most significant bits of the bit plane to the bit-sliced data for the least significant bits of the bit plane according to coding efficiency or according to a modified bit division coding method. The coded samples are packaged according to a structure of layers.
