Overview

VME-5550 Reflective Memory interface allows data to be shared between up to 16 independent VMEbus systems (nodes) at rates up to 20 Mbyte/s. Each Reflective Memory board may be configured with 256 Kbyte to 4 Mbyte of on-board SDRAM. The local SDRAM provides fast Read access times to stored data. Writes are stored in local SDRAM and broadcast over a high-speed parallel data bus 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.
 

  • Up to 4 Mbyte of Reflective Memory
  • Any node on the network can generate an interrupt in any other node on the network or in all network chassis simultaneously
  • No processor overhead
  • Multidrop capability (up to 16 nodes)
  • Data transferred at 20 Mbyte/s (50-foot cable)
  • High-speed, easy-to-use parallel network
  • Data written to memory in one node is also written to memory in all nodes on the network
  • No processor involvement in the operation of the network
