Method and apparatus for creating multi-gradation data. The method and apparatus generates data having pixel values for respective pixels which comprise each of a plurality of characters in a font, and divides the respective pixels into a plurality of unit regions, a number of the respective pixels being obtained by multiplying a desired number of pixels by a number of pixels included in one unit region of the plurality of unit regions; extracts, for every unit region of the plurality of unit regions, the generated data; generates a multi-gradation data including a plurality of gradation values each gradually representing a different pixel brightness value, by converting, for every unit region, the data into the multi-gradation data in accordance with a plurality of pixel values included in the extracted unit region; and reduces the number of the respective pixels to the desired number of pixels by representing each unit region including the number of pixels with one pixel having a pixel value determined in accordance with the multi-gradation value.

Method and apparatus for creating multi-gradation data

A microprogramming control system employing a plurality of low read rate control memories, for storing micro instructions, individually addressed in turn at a rate greater than the read rate of each memory. Each addressed control memory reads out a plurality of micro instructions. A selection circuit receives the plurality of micro instructions, in time shared fashion, read out in turn from each addressed control memory, then selects and gates a single micro instruction to a storage device. One portion of the selected micro instruction is designated as an address for the next micro instruction to be read out from the same control memory, and is accordingly gated to an address storage device at the input of the corresponding control memory.
