SDW 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
SDW TAORMINA The PCI model for the sequencer/interface board : Simplified PCI version for the sequencer/interface board PCI sequencer/interface board main functions
SDW 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
SDW 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
SDW 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
