Anisotropic texture filtering has been developed for a high quality three dimensional (3D) computer graphics and multimedia applications. This paper proposes an effective parallel multi-way set associative cache for anisotropic texture filtering, which can be adaptively reconfigured based on the number of probe samples. The proposed architecture also adopts a simple and efficient miss-fetch merge scheme to exploit the sequential access benefit. This paper constructs the trace-driven cache simulator in order to evaluate the proposed architecture. The benchmark suites for the simulation use OpenGL library. Experimental results show that the proposed 256KB cache architecture can reduce the memory access time of about 8.3% and 0.5% than the conventional 512KB and 1MB caches, respectively. Also, the hardware overhead is negligible.
