AbstractIn a pattern data conversion processing system, one-character pattern data generated by a character generator is divided by a shift register into a plurality of basic pattern data. The divided basic pattern data are sequentially subjected to enlargement, 90° conversion or nonrotational conversion by using a 4/3 times elongation conversion ROM, a double elongation/90° conversion ROM and a bypass circuit. The converted one-character data is stored in a one-character ROM and, as such, the one-character pattern data from the one-character ROM is stored by a direct memory access controller (DMAC) into a frame memory. When 180° conversion is designated, the one-character data is subjected to 90° conversion, and the converted data is stored in the frame memory. The pattern data from the frame memory is transferred by the DMAC to a page printer which then prints the transferred data.
