PMC-5579

PMC-5579 Reflective Memory - interface allows data to be shared between up to 256 independent systems (nodes) at rates up to 13.4 Mbyte/s. Each Reflective Memory board is configured with 64 Mbyte of on-board RAM. The local RAM provides fast Read access times to stored data. Writes are stored in local RAM 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.
 

• Any node on the network can generate an interrupt in any other node on the network or in all network nodes with a single command
• Data transferred at 6.7 Mbyte/s with redundant transfer
• 13.4 Mbyte/s Fiber-Optic Reflective Memory with Interrupts
• High-speed, easy-to-use fiber-optic network (270 Mbaud serially)
• Data transferred at 13.4 Mbyte/s without redundant transfer
• Up to 6,000 m between nodes and up to 256 nodes using single-mode fiber optics
• Data written to memory in one node is also written to memory in all nodes on the network
• Up to 1,000 m between nodes and up to 256 nodes using multimode fiber optics
