Abstract:
A graphics drawing apparatus able to reduce the amount of data transferred, able to realize a lower power consumption, and consequently able to achieve an improvement of performance of the system as a whole, provided with address generator for automatically generating addresses of drawing parameter registers required for the drawing in a defined sequence of drawing parameters according to address data and a specified drawing type; a register address selector for selecting either of the address data for specifying the register addresses of the address generator transferred through a general purpose bus or the address data for specifying the register address of the address generator by a former engine and inputting the same to the address generator; and a drawing data selector for selecting either of the drawing parameter data transferred through the general purpose bus or the drawing parameter data from the former engine and inputting the same to the drawing engine, and a method of the same.
