Vision HDL Toolbox
Design image processing, video, and computer vision systems for FPGAs and ASICs
Vision HDL Toolbox™ provides pixel-streaming algorithms for the design and implementation of vision systems on FPGAs and ASICs. It provides a design framework that supports a diverse set of interface types, frame sizes, and frame rates. The image processing, video, and computer vision algorithms in the toolbox use an architecture appropriate for HDL implementations.
The toolbox algorithms are designed to generate readable, synthesizable code in VHDL® and Verilog® (with HDL Coder™). The generated HDL code is FPGA-proven for frame sizes up to 8k resolution and for high frame rate (HFR) video.
Toolbox capabilities are available as MATLAB® functions, System objects™, and Simulink® blocks.
Get Started:
Automated Driving
Start building your automated driving system with hardware-proven subsystems for lane detection, pothole detection, and stereo disparity computation.
Feature Detection
Learn how to implement feature detection techniques with streaming hardware to develop surveillance, object tracking, industrial inspection, and other applications.
Camera Pipeline
Jumpstart development of image conditioning hardware using examples of noise removal, gamma correction, and histogram implementations.
Image conditioning for an edge detection FPGA application.
Hardware-Accelerated Vision Processing
Model and simulate efficient hardware implementations of vision processing algorithms, such as conversions, filtering, morphology, and statistics. Then use HDL Coder to generate synthesizable VHDL or Verilog RTL.
HDL-ready Edge Detector block and its configurable parameters.
Processing Multiple Pixels Per Clock
Process 4k, 8k, or high-frame-rate video at FPGA clock rates by specifying parallel streams of 4 or 8 pixels. The underlying hardware implementation is automatically updated to support simulation and code generation with the specified parallelism.
Specify processing of up to 8 pixels in parallel.
Built-In Hardware Data Management
Use Vision HDL Toolbox blocks to automatically manage streaming input data, such as control signals, region-of-interest (ROI) windows, and line buffers. Use HDL Coder to generate VHDL or Verilog RTL for the control functionality you model and simulate.
Automatically buffer rows to create an ROI window for edge detection.
Conversion Between Frames and Pixels
Convert full-frame video to a stream of pixels with control signals for processing in hardware. Then convert the streaming hardware output to frames for verification against your golden reference algorithm.

MATLAB and Simulink Verification Examples and Templates
Learn how to use your Image Processing Toolbox™ and Computer Vision Toolbox™ algorithms and tests to verify your hardware implementation.
