<p>PURPOSE:To correctly decode a picture data into an original picture data by skipping reading of the picture data when there is no room for writing one frame of the picture data. CONSTITUTION:A game set main body 1 consists of a microcomputer (CPU) 11, a DMAC (DMA controller) 12, and a main RAM 13 for a work area or the like. Then before a compressed picture data is written in a buffer memory 13, whether or not a memory 13 has a vacant area for one frame of the picture data is checked by the CPU 11. As a result, when there is a room, the picture data is written in the memory 13, while no room is in existence, the compressed picture data is thrown away by the CPU 11 and the DMAC 12.</p> |
