Abstract: The present invention relates to a method and apparatus for encoding a displacement video using image tiling. A method for encoding multi-dimensional data according to an embodiment of the present disclosure may comprise: converting the multi-dimensional data into one or more frames with two-dimensional characteristics; generating one or more frame groups by grouping the one or more frames with pre-configured number units; reconstructing frames belonging to each frame group into a tiled frame; and generating a bitstream by encoding the tiled frame. Here, the tiled frame may be constructed with one or more blocks, and each block may be constructed by rearranging pixels existing at the same location in the frames.

The method of creating a tile-switch mapping architecture includes first, second and third calculating steps. The method of creating a tile-switch mapping architecture minimizes the hop distance between cores when the mapping relationship between cores and tiles is determined, to thereby minimize energy consumption and communication delay time in an on-chip bus. Furthermore, the method of creating a tile-switch mapping architecture presents a standard for comparing the optimization of other mapping architectures.

Abstract: A bus arrangement is provided including a master device and a slave device. A master converts a read command into a write command and sends the write command through a bus network within the bus arrangement and a slave device converts the write command back to the read command and sends a response. The response is sent on a bus not included within the bus network, thereby reducing a response delay time between the transmission of the read command and the response to the read command.
