Reflective Memory is an optical ring-based, ultra high-speed shared memory network solution. It allows a distributed network to share real-time data at a deterministic rate, regardless of bus structures and operating systems. With more than 15 years of experience in this field, J-Squared is an original pioneer of this technology and our 5565 Reflective Memory family extends our market leadership position.
How do we do it? We keep it simple. Our Reflective Memory technology is centered on an innovative and efficiently designed hardware platform that is easy to use, provides for greater distance between nodes, high noise immunity, optional node bypass, and no software overhead. Just read and write to the onboard memory and the Reflective Memory node controller does the rest.
The 5565 Reflective Memory family is available in multiple form factors, including PCI Express (PCIE5565RC), low profile PCI Express (PCIE-5565PIORC), PMC (PMC-5565PIORC), PCI (PCI 5565PIORC), and VME (VME-5565). The family allows computers, workstations, PLCs, and other embedded controllers to all share data in real-time. The transfer of data between nodes is software transparent so no processor overhead is required. Data written into the Reflective Memory is broadcast to all nodes on the network without further involvement of the sending or receiving nodes.
