GE VMIPCI-5565-110000 Reflective Memory

OVERVIEW

The VME-5565 Reflective Memory node card provides a high-speed, low latency, deterministic interface that allows data to be shared between up to 256 independent systems (nodes) at rates up to 170 Mbyte/s. Each Reflective Memory board can be configured with either 64 Mbyte or 128 Mbyte of onboard SDRAM. The local SDRAM 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 processor and bus performance to maintain high data throughput.
