Abstract: As a screen refreshing storage in a graphic processor a storage system 10 is presented that shows a very high access rate for data blocks used in graphic processors. For storing e.g. square data blocks, or for retrieving a row section of the display 23 only one storage access is required: this is a consequence of the specifically selected interleaving of the individual storage modules 16 and of data editing for the respective access formats. The two-dimensional addressing for storing the data block distributes the individual elements of the data block to the modules in such a manner that the same storage addresses of all modules finally present a full picture of a row sectinn of the display. Between processor 1 or 7 and storage 10 a block buffer 4 is also provided operating in pingpong mode.
