Abstract :
A triangle setup engine (TSE) generates setup parameters for rasterization in 3D graphics hardware. Since the TSE must be flexible for various embedded systems, a programmable TSE is proposed, especially optimized for a division-free rasterizer and it shows a performance improvement up to 4.76 times, derived by a 3-way SIMD architecture with special instructions for matrix-vector multiplication. It is integrated with an optimized format converter in 0.13 μm CMOS technology. Its gate count is 210 kgates and the power consumption is 49.1 mW at 166 MHz operation frequency.
