A data access method applicable on an electronic apparatus is provided. The electronic apparatus comprises a control unit, a first storage apparatus, and a second storage apparatus. The method comprising: storing a first part of data and a second part of data of a data group in the first storage apparatus and the second storage apparatus, respectively; and selectively accessing the first storage apparatus and the second storage apparatus via different data paths for the first part of data and the second part of data, wherein access speed to the first storage apparatus is different from access speed to the second storage apparatus.

Data accessing method and electronic apparatus utilizing the data accessing method

A quantized coefficient coding apparatus used in a media coding system includes a determination module, a coding mode arbitration module and a coding module. The determination module determines whether a set of quantized coefficients are defined in a predetermined variable length coding (VLC) table to generate a determination result. When the determination result of the determination module is negative, the coding mode arbitration module determines a best coding mode corresponding to the set of quantized coefficients from a plurality of predetermined coding modes. The coding mode encodes the set of quantized coefficients according to the best coding mode.
