Product Specifications

Technical details and manufacturing context for Host Bus Interface Controller

Definition
A specialized integrated circuit or chipset within a Frame Grabber or Vision Interface Card that serves as the primary interface controller, managing the protocol conversion, data buffering, and timing synchronization required to transfer high-speed video/image data from the camera interface to the computer's main system bus (e.g., PCIe, PCI-X, PCI). It handles bus arbitration, DMA (Direct Memory Access) operations, and ensures reliable data transmission with minimal CPU overhead.
Working Principle
The controller receives parallel video data streams from the camera interface circuitry (e.g., Camera Link, CoaXPress, GigE Vision). It converts this data into packets compliant with the host bus protocol (e.g., PCIe transactions). Using onboard buffers and FIFOs, it manages data flow to compensate for speed differences. It implements bus mastering DMA to write image data directly to system memory, generates interrupts to signal frame completion, and responds to configuration commands from the host CPU over the bus.
Common Materials
Silicon (for IC die), Ceramic or plastic (for package), Copper (for interconnects)
