3D LUT Intel® FPGA IP
Overview
3D LUT Intel FPGA IP provides an efficient solution for video color-space conversions and conversion between nonlinear gamuts. This IP also enables many other artistic and cinematic effects, such as sepia tone, monochrome, color changes, vintage, vivid color, cool/warm film and the ability to create chroma-keys to separate foreground from a colored background. The 3D LUT IP employs Tetrahedral interpolation. The 3D LUT IP uses the most significant bits (MSBs) of the 3-color component inputs to retrieve data values from the contents of the LUT (in FPGA memory), and the least significant bits (LSBs) to interpolate the final output value. The interpolation processes and memory methods used in Intel’s 3D LUT IP use a lower number of gates and memory than competing solutions, enabling practical 3D LUT implementations using an FPGA for a more cost-effective solution. The low resource count and industry standard interfaces such as AXI4-Streaming and AXI4-Lite allow the IP to be easily integrated into your Intel FPGA design.
