3D LUT Intel® FPGA IP

Overview

As a part of the Video and Vision Processing (VVP) Suite Intel® FPGA IP, the 3D look-up table (LUT) Intel® FPGA IP provides an efficient solution for video color space and dynamic range conversions, chroma keying, and the creation of artistic effects.

3D LUT Intel® FPGA IP Offers Efficient Video Solutions By:

  • Enabling various artistic and cinematic effects.
  • Supporting SDR to HDR, HDR to HDR, and HDR to SDR conversions and PQ/HLG and log-transfer functions.
  • Supporting cube sizes of 9³, 17³, 33³, and 65³.
  • Applying tetrahedral interpolation.
  • Utilizing industry-standard interfaces to ease the integration into your FPGA design.
  • Minimizing resource utilization compared to competing products enables a more cost-effective solution.

Key Features

  • Support up to 4 pixels in parallel (PIP) per clock processing.
  • Low subframe latency (21 clock cycles).
  • Support for 17³, 33³ and 65³ LUTs.
  • Support 3 and 4 output channels from the LUT (Alpha /key channel).
  • High-quality tetrahedral interpolation.
  • Independently set input/output pixel depth.
  • Independently set LUT precision.
  • Dynamic update of table values with optional double buffering to enable clean synchronous switching to a new LUT.
  • Includes ‘.cube’ file format conversion utility.
  • Support for 8, 10, 12, and 16-bit per color component.
  • Support resolutions up to 4K at 60 fps on Intel® Cyclone® 10 FPGAs, Intel® Arria® 10 FPGAs, Intel® Stratix® 10 FPGAs, and Intel Agilex® 5 FPGA E-Series.
  • Support resolutions up to 8K at 60 fps on Intel Agilex® 7 FPGAs and on Intel Agilex® 5 FPGA D-Series.
  • AXI4-Stream video I/O interface.
  • AXI4-Stream ↔ Avalon® streaming interface protocol converters.
  • Avalon® memory-mapped CPU control and memory interfaces.
  • Low resource utilization for edge applications.
  • Free Intel® FPGA IP Evaluation Mode.
  • Design example available.
