Abstract
PURPOSE: To enable to rotate, extend and shrink the two-dimensional pattern memory in high speed, by using the carry over or down signal to the input clock given to the signal line and performing the control of addition and subtraction.
CONSTITUTION: The two-dimensional pattern memory 300 stores or reads out the two dimensional dot pattern quantized with the dot matrix. Further, the external input indicated in the adder 420 and the register 410 is sequentially added or subtracted to give initial value to the signal line 8003, and carry over or down signal is used to the input clock given to the signal line 8001 and control is made that the adders 410, 430, 520, and 550 are operated. Further, numeral 1 is fixedly given to the signal line 8004, and the output of count up or down incremented or decremented by 1 is outputted by using the signal line 4101. Thus, the two-dimensional pattern memory can be rotated, extended and shrinked in high speed.
