Project Main Requirements

• Upgrade for the precedent generation of
  transputer based VME/VSB boards saving
  compatibility with high
• level SW (table editors)
• 2. Compatibility with modern bus architecture,
  I.E. PCI, CPCI, VME and modern bus-adapters
  (AMCC chips)
• Use of host computer memory for data storage via
  PCI fast data transfers
• Use of fast throughput, full-duplex, data
  controls link between host interface and remote
  electronics
• On board (host interface) generation of detector
  clock sequences and transmission through the fast
  control link

The PCI model for the sequencer/interface board
Simplified PCI version for the sequencer/interface
board
PCI sequencer/interface board main functions
4
The PMC model for the sequencer/interface board
Dual slots PMC piggy-back detector
interface mounted on a Motorola C-PCI CPU
The PMC module can be mounted in a variety of
VME/C-PCI boards. It implements the same concept
found on the PCI version with the presence of a
large, host computer, configurable FPGA dedicated
to the implementation of fast local functions on
the data-flow
PMC sequencer detector Interface main functions
5
The Remote Glue Logic Board
Example of Glue-Logic remote board with
programmable clocks, services, telemetry and
system bus implemented on a 8 layers SMD
double-euro card
Glue-Logic is embedded on a Xilinx FPGA. It
provides communication with the PCI/PMC host I/F
board and all the logics for the implementation
of a detector controller in a scalable way

System Expansion for High Number of Video
Channels
GLUE-LOGIC BOARDS
A common synchronization line driven by a master
PCI/PMC interface allows expansion to a
distributed acquisition system.
