A general purpose reflective memory board for accelerator data acquisition and control system applications

The demonstrator of a reflective memory board for particle accelerators data acquisition and control system applications is presented. The main building blocks of the reflective memory board are: a 32 bit times 66 MHz Master/Target PCI interface with DMA capabilities, a fiber optic full-duplex high-speed link and a 1 MByte synchronous static DPRAM. The reflective memory mechanism is implemented in a fully transparent way in both directions. A message passing and remote interrupt generation procedure from one PC to the other is implemented too
