GE VMIVME-5531S-000 Slave VMEbus Fiber-Optic Repeater Link

Product Overview

-The Reflective Memory concept provides a very fast and efficient way to share data between distributed computer systems.

VMIC's VMIVME-5576 Reflective Memory interface allows data to be shared between up to 256 independent systems (nodes) at rates of up to 6.2 Mbyte/s. Each Reflective Memory board can be configured with up to 256 nodes.

Each Reflective Memory board can be configured with 256 Kbytes to 1 Mbyte of on-board SRAM. local SRAM allows fast reads of stored data.

Write data is stored in the local SRAM and broadcast to other Reflective Memory nodes via a high-speed fiber optic data path.

Data transfers between nodes are software transparent, so there is no I/O overhead.

Transmit and receive FIFOs buffer data during peak data rates to optimize CPU and bus performance and maintain high data throughput.

Reflective memory also allows interrupts to one or more nodes by writing to byte registers.

Data Acquisition

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 up to 170 Mbyte/s. Each Reflective Memory board may be configured with 128 MB or 256 MB 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 the host computer and bus performance to maintain high data throughput.
