VMIC VMIVME-5576 Reflective Memory Module. VME Fiber-Optic Reflective Memory with Interrupts | VME bus | 175 Mega Baud Reflective Memory | Up to 2,000 m between nodes and up to 256 nodes Simple Type: Reflective Memory Module
VMIC’s VMIVME-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 SRAM. The local SRAM provides fast Read access times to stored data. Writes are stored in local SRAM 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.
