Method and device for decoding moving picture

Abstract

A memory control part 12 cyclically assigns time slots to buffer memory parts 21 to 25 respectively and in each time slot, controls access between the corresponding buffer memory part and a synchronous RAM 11. A time slot is determined while assuming the worst case where access to the synchronous RAM is the severest. Time slot groups of [(the number of pixels on one horizontal scanning line)/256] in number are generated in an imaginary one horizontal scanning period, where [ ] denotes an integer portion of the number in the parentheses. For a buffer memory 22 whose data volume changes depending on a compression factor, a time slot ending point may be made variable, or a time slot may be generated by interrupt as an exception.
