MEN Mikro P512 - Reflective Memory PMC

4 Independent Channels, -40 to +85°C Operation


The P512 offers Reflective Memory functionality, for example for redundant computer structures in safety-critical applications. Reflective memory is a memory bus technology from Encore Computer that allows simultaneous reads and writes to multiple memories. It can be used to share memory among multiple CPUs. The advantage of reflective memory is the possibility to set up deterministic real-time communication networks across computer systems and operating systems.

Each P512 module offers one LVDS channel. The modules can be interconnected in a fully connected mesh and support multi-mode up to two meters. Each computer in a system needs one PMC for each connection to another computer (2 computers: 1 PMC each, 3 computers: 2 PMCs each etc).

The module is equipped with 32 MB DDR2 DRAM.

The P512 is a PMC mezzanine card suitable for any PMC compliant host carrier board in any type of bus system, i.e. CPCI, VME or on any type of stand-alone SBC in telecommunication, industrial, medical, transportation or aerospace applications. It supports 32 bits/33 MHz. Appropriate PMC carrier cards in 3U, 6U and other formats are available from MEN or other manufacturers.
