<p><P>PROBLEM TO BE SOLVED: To provide a video coding-decoding device capable of maximizing system performance using limited memory resources. <P>SOLUTION: The video coding-decoding device 100 generates a DMA (Direct Memory Access) request, after a DMA means 160 of a motion compensation apparatus 101 receives the completion of interpolation from an interpolating means 180. According to the maximum DMA burst constraint and the block buffer size constraint, the video coding-decoding device receives a plurality of DMA input data, after a DMA ACK (Acknowledgement) is received from a memory access intervention means 110. According to the decoding parameters, operation process level Lc, maximum DMA burst constraint, and block buffer size constraint, the video coding-decoding device generates a block memory address for storing reference pixel data in the variable size block buffer 170. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
