2. SDW2005 - TAORMINA Project Main Requirements: 1.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) 3.Use of host computer memory for data storage via PCI fast data transfers 4.Use of fast throughput, full-duplex, data & controls link between host interface and remote electronics 5.On board (host interface) generation of detector clock sequences and transmission through the fast control link

3. SDW2005 - TAORMINA The PCI model for the sequencer/interface board : Simplified PCI version for the sequencer/interface board PCI sequencer/interface board main functions

4. SDW2005 - TAORMINA Dual slots PMC piggy-back detector interface mounted on a Motorola C-PCI CPU PMC sequencer & detector Interface main functions The PMC model for the sequencer/interface board : 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

5. SDW2005 - TAORMINA 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 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

6. SDW2005 - TAORMINA System Expansion for High Number of Video Channels: A common synchronization line driven by a master PCI/PMC interface allows expansion to a distributed acquisition system. GLUE-LOGIC BOARDS
