VMIC VMIPCI-5576 Fiber-Optic Reflective Memory Card with Interrupts | PCI bus Simple Type: Reflective Memory Module
PCI-5576 Reflective Memory interface - allows data to be shared between up to 256 independent systems (nodes) at rates up to 6.2 Mbyte/s. Each Reflective Memory board may be configured with 256 Kbyte to 1 Mbyte of on-board SDRAM. The local SRAM provides fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high-speed fiber-optic data path to other Reflective Memory nodes. The transfer of data between nodes is software transparent, so no I/O overhead is required. Transmit and Receive FIFOs buffer data during peak data rates to optimize CPU and bus performance to maintain high data throughput.
