Vision Processors: Embedded Power for Real-Time Processing


Xclera CL VX4 vision processor

Teledyne DALSA vision processors feature powerful embedded processing architecture for real-time high-performance machine vision applications. Combining high-speed image acquisition capability with user programmable FPGAs (Field Programmable Gate Array) and graphical FPGA development tools, our vision processors deliver unmatched power and flexibility in real-time image processing on the PCIe platform.

When do I need a Vision Processor?

  • When protecting your custom algorithm IP is paramount
  • When you need real-time, deterministic response
  • When the processing bandwidth is too high for a PC to handle
  • When you must reduce system footprint (e.g. multiple PCs are not an option)

Develop, Deploy, and Debug Embedded Solutions with Real-Time Performance

Our general purpose programmable vision processors feature an FPGA hardware processing platform that combines ACU(Acquisition Control Unit), DTE (Data Transfer Engine) and IPU (Image Processing Unit) and state of the memory architecture. As a result, models such as our new Xcelera-CL VX4 are capable of handling variety of complex, real-time image processing topologies including iterative processing loops. While the FPGA technology provides ability to adapt to variety of high-speed, compute-intensive real-time processing applications, the Xcelera VX4 hardware design has been implemented using standard off-the-shelf components with long term availability.

Key Features:

  • Highly optimized memory architecture for embedded image processing
  • Up to 2 x 512MB of Image memory
  • Up to 4 x 32MB of image processing memory
  • Extensive camera support
  • User configurable Xilinx Virtex 5 FPGA

Sapera APF


Sapera APF is an integrated graphical FPGA development environment. The Sapera APF simplifies traditional FPGA development processes by combining a point and click graphical interface with FPGA based image processing libraries. Sapera APF comes bundled with a bit accurate software version of the FPGA library functions for rapid functional simulation but also automatically generates necessary infrastructure to call user functions using Sapera SDK. This powerful, yet easy to use FPGA development environment allows users to create, debug, and deploy FPGA code without ever leaving the development GUI, dramatically improving ease of development and time to deployment.
