DEVICE FOR CONVERSION OF COORDINATES Russian patent published in 1994 - IPC

FIELD: computer engineering. SUBSTANCE: device has vector rotation unit 1 having two arithmetic units 2, 3, horizontal and vertical coordinate registers 4 and 5 and corresponding functional connections. In addition device has register 6 for holding initial abscissa value, abscissa displacement register 7, register 8 for holding initial ordinate value, ordinate displacement value 9, distance register 10, two angle registers 11 and 12, abscissa counter 13, ordinate counter 14, distance counter 15, two angle counters 16, 17, three decoders 18, 19, 20, control unit 21 and corresponding functional connections. EFFECT: increased field of application due to possibility of rotation of image parts and standalone points about arbitrary rotation point. 3 cl, 3 dwg
