High Speed Video Processing Using Fine-Grained Processing on FPGA Platform

This summary paper(1) proposes an FPGA-based array processor which performs Laplacian filtering on a 40 by 40 pixel grayscale video. The architecture comprises of bit-serial pixel processors interconnected to give a two-dimensional mesh array. This architecture features the novel use of partial reconfiguration which transfers data to and fro the array. Each processor occupies a configurable logic block and achieves a target frame rate of 10000 frames per second, at an operating frequency of 0.31 MHz on the Virtex-6 ML605 Evaluation Kit. The detailed correspondence between the contents of slice lookup tables and the Virtex-6 bitstream format is also documented.
