<P>PROBLEM TO BE SOLVED: To provide a data access circuit capable of speeding up access to data stored in a memory with a simple configuration, and to provide a decoder, an information reproducing device, and electronic equipment thereof. <P>SOLUTION: A data access circuit 10 includes: an M-bit buffer (M≥n+m, M: a positive integer) for storing data read from the memory; and a pointer management section for managing the pointers of the M-bit buffer. When there is a read request from an external module and the remaining number of data stored in the M-bit buffer is smaller than n bits, control for replenishing data from the memory to the M-bit buffer is made, and the pointer is updated so that the remaining number of data becomes larger by m bits. When there is a read request and data stored in the M-bit buffer are not less than n bits, control for outputting from the M-bit buffer to the external module is made, and the pointer is updated so that the remaining number of data becomes smaller by n bits. <P>COPYRIGHT: (C)2008,JPO&INPIT |
