A memory management method is provided. In the method, a spatial parameter included in an encoding result is represented as a vector of a time slot and a frequency band in a first domain, a temporary matrix is calculated in the first domain by using the difference between vectors of a current time slot and a previous time slot at the same frequency band and then is stored in a memory, and then a matrix needed to decode the encoding result is represented as a matrix for a time slot and a frequency band in a second domain by using the temporary matrix, thereby reducing the load on the memory for storing matrices on which a decoding operation is performed.

A method and apparatus for implementing fixed codebooks as a common module are provided. In the method of implementing fixed codebooks of a plurality of speech codecs as a common module, it is possible to include only a part excluding fixed codebooks in a communication terminal or communication system, support various speech codecs without using a chip with high price and high performance, and reduce a memory space that is occupied by the speech codecs by generating a track of a fixed codebook corresponding to a speech codec based on information on the speech codec among the plurality of speech codecs and selecting a codebook vector corresponding to a target signal among codebook vectors constructed with combinations of pulses represented by the generated track. In addition, it is possible to reduce processing complexity as compared with a case of embodying the common fixed codebook module in software by embodying the common fixed codebook module in hardware. In addition, it is possible to improve the entire voice processing performance by applying the latest fixed codebook searching algorithm only to the common fixed codebook, thereby easily applying the latest fixed codebook searching algorithm to the entire voice codec.

Provided is printer operation control system and method for a printer having diverse print functions by using an external memory. The external memory is used to store information on the availability of each print function. A reader is provided for reading the information on the availability of each print function stored in the external memory. Further, a function setting unit is provided for setting up the operability of software for each print function based on the information read in the reader. Even further, a controller is provided for controlling the operation of the printer based on the operability of each software set up in the function setting unit.

A method, medium, and system effectively compressing and/or restoring binary images. By compressing pixel values making up a 2×2 block in an input image, using representative values representing the pixel values and a pattern of the pixel values represented by the representative values, it is possible to effectively compress and/or restore binary images having little similarities between pixel values. In addition, by extracting compressed values and a pattern of pixel values making up a 2×2 block in an image, from compressed data of the 2×2 block, and restoring pixel values using the compressed values and the pattern, it is possible to effectively restore binary images.
