Picture processing apparatus for handling command data and picture data

摘要

When a storage unit 18 records the title of a picture or the like with the ASCII codes along with the picture data and reads out the data for transfer. A DMAC controller 2a transfers the ASCII codes along with the picture data stored in a buffer circuit 22 in a lump to a frame memory 1 at a high transfer speed without interposition of a CPU 8. The memory controller 2 interprets the ASCII codes stored in the frame memory 1 to form picture data of letters or characters associated with the ASCII codes and writes the data in the frame memory 1. The picture data stored in the frame memory 1 is read out and routed to a monitoring device 15 so that the letters or characters associated with the ASCII codes are displayed along with a picture corresponding to the picture data.
