The Advme1522A is a shared memory board used for sharing data between distributed systems using multi-mode optical fiber.
Only the resistor for default settings and shared memory area can be accessed from software.
It is ideal for linking remote systems and for linking VME bus systems with PCI systems. It performs built-in communication function with a bit rate of 250Mbit/s and data communication speed of 4MB/s.
The mapping of shared memory area can be modified and memory size can be expanded.
The board provides also a built-in adjacent node failure and cable break detection function.
Added CRC and data backup is performed to ensure high reliability of communications.
Shared memory with PCI bus possible (byte endian swap function).
