Abstract
Disclosed herein is a memory system for storing a two dimensional digitized image signal consisting of a plurality of pixels arranged in (2.sup.M +X) columns and (2.sup.N +Y) rows, wherein X and Y do not exceed 2.sup.M-2 and 2.sup.N-1 respectively, and M and N are integers, comprising: a virtual address generator for generating (M+N+2) bits of a virtual address having (M+1) bits of a horizontal address component representing said (2.sup.M +X) columns and (N+1) bits of a vertical address component representing said (2.sup.N +Y) rows; a memory, having storage locations of 2.sup.M+N+1, for storing the two dimensional digitized image signal, each of the storage locations capable of storing one pixel data therein and addressable by (M+N+1 bits) of a physical address; and address mapping circuitry for changing the virtual address to the physical address.
