Abstract
PURPOSE: To enable write-in, erase and superimposed memory from arbitrary coordinate axis, by shifting new input data, when the input address data designates the location on the way of one given work length at the adjacent address to the memory.
CONSTITUTION: Since the input to the RAM 14 is made in one byte (8-dots) in the data processor, to write-in one byte from an arbitrary coordinate on the way of a given work length of the address of RAM 14, it is required to shift the input data. In this case, since the data length is 23, and since the lower rank 3-bit value of the coordinate value 21 at the X axis inputted to the address register 19 is the value showing from what dot the data is inputted, the data in the register 1 is shifted according to this value, the outputted with shift is entered to the register 2, and this shift is made as to the register 4 simultaneously. That is, when the value at the lower 3-bit of the coordinate value 21 is "5", the new data is contained to the registers 1, 2 with bridge as shown in (a), and the register 4 is as shown in (b).
