ABSTRACT:
Disclosed is a multi-dimensional parallel storing device, particularly for use in digital storing of picture elements scanned according to a scanning pattern. The device includes a plurality of multi-dimensional storage elements each being provided with an address-computing circuit. The address-computing circuit is assembled of a subcircuit for the recursive computation of a storage element of a distinguished or reference array point for a linear storing function after shifting of the window; a subcircuit for recursive computation of a reference array point for an isotropic addressing function; a translator for isotropic, preferably linear, storing function to determine a spacing vector of an array point for which the address computation is being performed and which is stored in a storage element pertaining to the referenced array point; and an arrangement for ascertaining the address of an arbitrary storage element. The storage arrangement of this invention is suitable for use in high-speed computers and operates with short binary words and enables access to all types of memory windows, such as rectilinear, flat or spatial. The address-computing circuit of this invention requires only the data about coordinate changes and about the preceding memory window and the coded designation of the window. The address computation is recursive.
