Abstract

Provided is a graphics rendering device that includes a frame data generation unit, access pattern setting unit, and frame data writing unit. The frame data generation unit generates, from part of stencil data, a part of frame data composed of a piece of second pixel information corresponding to a predetermined number of pixels in accordance with a first access pattern and an anti-alias pattern used in generating pieces of second pixel information. The access pattern setting unit sets, in accordance with the first access pattern and the anti-alias pattern, a second access pattern indicating pieces of second pixel information accessible by a single access to the frame buffer. The frame data writing unit writes in the frame buffer, when the frame data generation unit has generated a number of pieces of second pixel information indicated by the second access pattern, a part of the frame data corresponding to the number of pieces of second pixel information in accordance with the second access pattern.
