Abstract
A multimedia processor for performing three dimensional graphics processing in an integrated circuit comprises a microprocessor circuit which is configured to generate triangle set-up information corresponding to a plurality of triangles that define a three-dimensional object displayed on a screen. The screen is defined by a plurality of bins having a predetermined number of pixels. A data cache is coupled to the microprocessor and configured to store the set-up information. A three-dimensional triangle rasterizer is coupled to the data cache and configured to perform bin allocation to the triangles so as to identify all bins that intersect with a triangle on the screen.
