V124
VXI Fiber Optic FOXI PCI Host Adapter

The KineticSystems FOXI interface provides a fiber optic connection between a PCI-based host computer or workstation and one or more VXI mainframes to provide a high-throughput, deterministic data acquisition and control system.

The fiber optic based FOXI system supports distances between nodes up to 2 km (6,560 ft) with an I/O throughput up to 10 MB/s. A complete FOXI system includes a V124 fiber optic FOXI host adapter, up to 126 V120 VXI fiber optic slot-0 controllers and a fiber optic cabling highway.

The V124 FOXI Host Adapter is a single PCI (Peripheral Component Interface) card which provides the interface between the PCI bus and the FOXI highway. Communication between this adapter and the host computer is via a 32-bit data path that is used to configure the system and initiate highway operations. A DMA (direct memory access) mechanism is incorporated to transfer data over the highway using 32-bit data transfers. The V124 supports PCI DMA transfers, yielding a 20 MB/s burst transfer rate.

Data transfers to and from a VXI mainframe are executed in a pipeline mode. These transfers will occur at the full 10 MB/s highway speed if both the source and destination can maintain the data rate. The V124 contains a 2048-word FIFO memory that stores asynchronous demand messages received from a V120 Slot-0 controller. These demand messages are generated from an interrupt in a VXI chassis. The demand data identifies the chassis that sourced the demand message as well as the source of the interrupt.
