Cache memory device for storing image data |
摘要 |
A cache memory device stores image data which are arranged corresponding to address data having first and second two-dimensional coordinate data. The image data are divided into a plurality of first groups in accordance with the first two-dimensional coordinate data, with the first groups further divided into a plurality of second groups in accordance with the second two-dimensional coordinate data. The cache memory device includes an image data memory for storing a given image data therein, which is divided into a plurality of block areas arranged in two dimensions. The reading and writing of image data from and to the image data memory is controlled by a central processing unit. A cache storage, comprising a cache memory, an address data decoding circuit, an address matching circuit and a control circuit, is coupled between the image data memory and the central processing unit by way of buses.
