Abstract
Disclosed is an improved computer graphics memory architecture. The architecture includes an address translation table (ATT) and a buffer. The address translation table receives information about desired pixel data and determines the physical address of the desired data. The buffer is connected to the ATT and has a dual bank which stores the color value and the Z value of a 3-D pixel. A buffer addressing method is also provided in which the address of the desired pixel information and associated control circuits may be quickly determined through an appropriate data arrangement in the buffer and an address transfer table.
