    • An image data transfer method including the steps of: (a) reading pixel data of a two-dimensional image stored in a first image storage and having a plurality of pixels, the position of each of the pixels being represented by coordinates of first and second directions, the pixel data being read by scanning data transfer units of the pixel data in the second direction where each of the data transfer units is formed by data of a predetermined number of pixels consecutive in the first direction; (b) writing the data transfer units read at step (a) in a temporary data storage where data is stored at a position designated by a combination of first and second addresses, the data transfer units being written in burst mode in a region of the temporary data storage in which the first addresses are consecutive while the second address is fixed; and (c) reading the data transfer units written in the temporary data storage from the region in which the first addresses are consecutive while the second address is fixed in burst mode and writing the read data transfer units in a second image storage.
    • 一种图像数据传送方法,包括以下步骤:(a)读取存储在第一图像存储器中并具有多个像素的二维图像的像素数据,每个像素的位置由第一和第二像素的坐标表示 通过扫描第二方向上的像素数据的数据传送单元来读取像素数据,其中每个数据传送单元由在第一方向上连续的预定数量的像素的数据形成; (b)将在步骤(a)读取的数据传送单元写入临时数据存储器,其中数据存储在由第一和第二地址的组合指定的位置处,数据传送单元以突发模式写入 临时数据存储,其中第一地址是连续的,而第二地址是固定的; 以及(c)从第一地址连续的区域读取临时数据存储器中写入的数据传送单元,同时在突发模式下读取固定第二地址的区域,并将读取的数据传送单元写入第二图像存储器。
