How is vision processor different from a frame grabber?
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, vision processors deliver unmatched power and flexibility in computer-intensive, real-time image processing on the PCIe platform.

When do I need a vision processor?  
• When protecting a custom algorithm IP is paramount • When a real-time, deterministic response is needed
• When the processing bandwidth is too high for a PC to handle • When the system footprint must be reduced (e.g. multiple PCs are not an option)

Vision processor and software work as a team
Teledyne DALSA's Xcelera-CL VX4 and Sapera APF deliver a powerful, programmable, FPGA- (field-programmable gate array) based vision processor and integrated graphical FPGA development environment enabling users to adopt vision processors for a variety of high speed, computing intensive, real-time image processing applications. Accessible to non-FPGA experts.

The Xcelera-CL VX4 series vision processors is the latest member of Teledyne DALSA's award winning Xcelera family of frame grabbers and vision processors and is based on the PCI Express x4 interface. Compatible with a Base, Medium or Full Camera Link® camera, the Xcelera-CL VX4 Full supports a wide variety of multi-tap area and line scan colour and monochrome cameras.

The Xcelera-CL VX4 Full, features 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, its powerful, user- programmable embedded processing architecture is capable of handling variety of high-performance, complex, real-time image-processing topologies including iterative processing loops.

While harnessing the power of field-programmable gate arrays, the Xcelera-CL VX4 is also accessible to non-FPGA experts and OEMs not only benefit from the real-time execution capabilities of FPGA but also from IP preservation, shorter development cycles and being able to leverage the simplicity of a standard, off-the-shelf processing platform.

Although FPGA technology provides the ability to adapt to a variety of high-speed, computer-intensive and real-time processing applications, the Xcelera-CL VX4 hardware design has been built using standard off-the-shelf components with long term availability.
