Abstract
A method and a device of consistency buffer for a high performance 3D graphic accelerator is disclosed to retain consistency without detecting any overlapping region in advance but determining an overlapping with respect to a rendered pixel. The device of consistency buffer according to the present invention comprises a fetch section for transmitting a plurality of primitives to be processed to a vacant region of the buffer, an issue section for buffering the plurality of the primitives transmitted from the said fetch section, and allotting positions to be inputted, a plurality of rendering accelerators for receiving and rendering the plurality of primitives allotted by the issue section, a consistency buffer for storing information required for processing with consistency according to a depth value and a color value of each primitive computed by each of the rendering accelerators, and a memory interface unit for performing read/write computation in a memory by mens of processing with consistency in order based on the information stored in the consistency buffer.
