The microEnable IV Series of frame grabbers from Silicon Software GmbH, Mannheim, Germany, have PCI Express interfaces and use an FPGA as the vision processor and image processing center of the device. Models are available to support CameraLink and GigE cameras. Operational functionality is implemented in applets, a hardware programming code for FPGA vision processors, that provides image acquisition as well as advanced image preprocessing functions. The boards are equipped with interfaces for PXIe x1 (single lane) up to PCIe x4 (quad lanes). The MicroEnable IV AD4-CL (CameraLink) and AQ4-GE (GigE) have a 256 MB image buffer, a 760 MBps transfer rate, and PCIe x4.
