ABSTRACT

ETexture mapping is a technique used for adding reality to an image in 3D graphics. However, this technique becomes the bottleneck of the 3D graphics pipeline because it requires large processing power and high memory bandwidth. For reducing memory latency in texture mapping, texture cache is used. As portable devices become smaller and they have power constraint, it is important to reduce the area and the power consumption of the texture cache. In this paper, we propose using a small texture cache to reduce the area and the power consumption of the texture cache. Furthermore, we propose techniques to keep a performance comparable to large texture caches by using prefetch techniques and a victim cache. Simulation results show the proposed small texture cache can reduce the area and the power consumption up to 70% and 60%, respectively, by using 1~2K bytes texture cache compared to the conventional 16K bytes cache while keeping the performance.
