Dynamic Noise Texture Generation on FPGAs

In this paper,a procedural texture mapping method based on Perlin noise function is designed and implemented on an FPGA programmable board.During the implementation,we take advantage of FPGA hardware design to better deal with the intensive per-pixel computation in the algorithm.Based on this method,naturally-appearing material effects like wood,marble and cloud can be generated in real time.The generated textures can be dynamically varying and get to real moving effect.In the paper,a novel Perlin noise function is adopted,targeting to the circuit structure with low cost of hardware resources,and the arithmetic units such as addition and multiplication modules are highly reused in the circuit design.
