Dynamic noise texture generation on FPGAs

FPGA technology provides a fast prototyping way to implement various algorithms on its reconfigurable hardware platform. It can flexibly handle different applications. In this paper, procedural texture mapping based on the Perlin noise function is implemented on a Xilinx FPGA prototyping board. Hardware design can deal with this intensive per-pixel computation much better. Realistically and interestingly natural-appearing material effects like wood, marble and fire can be generated and dynamically varying. A new Perlin noise function is adopted which is targeted to circuit structure with low cost of hardware resources. Arithmetic units such as addition and multiplication modules are highly reused in the circuit design.
