PATTERN PROCESSING SYSTEM

摘要

A pattern storage processing system for use with a page printer has a pattern storage for storing dot matrix patterns representing various characters, etc. Each pattern comprises plural portions called "squares", each of which consists of nxn bits. A selected pattern is transferred square by square from the pattern storage to a raster buffer via a rotator which rotates each square according to orientation information. Successive storage locations in the raster buffer which are to receive successive squares are designated by the combination of a base address in a register and offsets in an offset table.
