Abstract:
A graphics processing circuit, comprising:a primary memory that includes a primary color buffer and a primary Z buffer; a secondary memory that includes a secondary color buffer and a secondary Z buffer; a primary processor operably coupled to the primary memory, wherein the primary processor processes a first portion of image data for a frame, wherein processing the first portion stores color data for the first portion in the primary color buffer and Z data for the first portion in the primary Z buffer, wherein the primary processor includes a display driver, wherein the display driver generates a display signal from color data stored in the primary color buffer; and a secondary processor operably coupled to the secondary memory and the primary processor, wherein the secondary processor processes a second portion of the image data for the frame, wherein processing the second portion stores color data for the second portion in the secondary color buffer and Z data for the second portion in the secondary Z buffer, wherein the secondary processor receives a data transfer indication from the primary processor, wherein the secondary processor transfers color data for the second portion from the secondary color buffer to the primary color buffer in the primary memory based on the data transfer indication.
