Addressing process for the storage of image blocks

The invention relates to an addressing process for the storage of data in memories of SDRAM type. The process for storing, in pages of a memory, image blocks (h, v) consisting of v lines of h pixels, for the reading of image blocks (H, V) consisting of V lines of H pixels, is characterized in that t...

More Information
Summary:The invention relates to an addressing process for the storage of data in memories of SDRAM type. The process for storing, in pages of a memory, image blocks (h, v) consisting of v lines of h pixels, for the reading of image blocks (H, V) consisting of V lines of H pixels, is characterized in that the horizontal shift D, in terms of number of blocks (h, v), of the boundary of a page corresponding to any row I of the image with respect to the boundary of a page corresponding to a row I+a is equal to:D=a D, ∀ positive integer a less than R=INT [(V−2)/v]+2,(INT corresponding to the integer part of the division)the value D, which corresponds to the shift between two successive rows being chosen such that:D (B−1), with B=INT [(H−2)/h]+2.Applications relate, for example to motion estimation and motion compression.
