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.

Vision Processing IP Blocks

Intellectual property (IP) blocks in Vision HDL Toolbox provide efficient hardware implementations for computationally intensive streaming algorithms that are often implemented in hardware, enabling you to accelerate the design of image and video processing subsystems.

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.

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.

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.

Verification Using Frame-Based Algorithms

Connect frame-based algorithms and test benches to streaming hardware implementations for efficient verification.

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.
