Dynamic packet size, 4 to 64 bytes of data, multi-mode fiber connection distance up to 300 meters, single-mode fiber connection distance up to 10km, up to 256 nodes, data written to the memory of one node will also be written to the memory of all nodes on the network.
High-speed, easy-to-use fiber optic network (serial 2.12 Gbaud) with transfer rates from 43 MB/s (4-byte packets) to 170 MB/s (64-byte packets, 128 MB or 256 MB SDRAM reflective memory.
Redundant transfer mode for additional error suppression, no processor overhead, no processor involved in network operations, PCI 64-bit 66 MHz transmission, 3.3 or 5V, single wide sandwich interface. An independent DMA channel where any node on the network can use a single command to generate interrupts in any other node on the network or in all network nodes.
The PMC-5565PIORC 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 of up to 170 MB/s. Each reflective memory board can be configured with 128 MB or 256 MB onboard SDRAM. Local SDRAM provides fast read access time to stored data. Writes are stored in local SDRAM and broadcast to other reflective memory nodes via high-speed fiber data paths. Data transfers between nodes are software-transparent, so there is no I/O overhead. Send and receive FIFO buffered data during peak data rates to optimize host and bus performance to maintain high data throughput. The PMC-5565PIORC is RoHS compliant and has improved PIO read performance and firmware that can be upgraded in the field.
