A device for storing and displaying graphic information having a storage unit for storing both blocks and rows of data and retrieving rows of data. The storage unit consists of two storage segments, with eight storage modules each, which can operate in an interleaved mode. This permits two-dimensional addressing which consists of distributing the individual elements of a data block over the various separately addressable modules of the storage unit so that no one module contains more than one element of the data block, and that all elements of the data block can be read out in one cycle through simultaneous access of all of the storage modules.

In a device for storing and displaying graphic information with a raster display having an image field, a storage unit comprising: a plurality of storage modules, each for storing one of a plurality of elements of a plurality of information blocks, each of said plurality of elements representing a row of the image field; a storage control for addressing said storage modules in a two-dimensional manner, such that (a) said plurality of elements of each of said plurality of information blocks are stored in successive ones of said storage modules, and that (b) the rows of the image field are stored in the modules in such a manner that storage locations of the same address within each of said plurality of storage modules store a row of the image field; and a data preparation unit receiving the graphic information and communicating with said storage control, said data preparation unit aligning the graphic information prior to storage in said plurality of storage modules and aligning in the inverse order graphic information from said plurality of storage modules prior to transferral to the raster display, said data preparation unit comprising a register whose capacity corresponds to at least the size of one of said plurality of information blocks, said register having a feedback for cyclic shifting.
