    VME Host Board (1)

    Overview

    General Requirements are:

    - Two different applications – TOTEM and CMS Preshower;

    - Different Data Density – TOTEM not need to concentrate data;

    (bit/channel/event), CMS ES need to reduce data (N-bits/channel/event)

    - VME interface (CMS) with possibilities of stand alone mode (USB).

    Selected Implementation:

    - Standard VME64x 9U Board with Mezzanines Cards;

    - Mezzanines Cards:

    “OptoRX” – 12ch Optical Receiver;

    “S-Link64” – standard CMS S-Link64 board;

    “VFAT Emulator” – 12 channels Optical Transmitter VFAT emulator;

    “DRM” – Data Reduction Module;

    - Upgrades Capabilities – modular design.

    Conclusions

    • VME Host Board is a complex design;

      • Need to cover several different requirements;

      • It is based on modular principle, therefore:

        • It is easy to develop and test separate mezzanines;

        • Build unit not fully equipped (cost, performance);

        • Easy to Upgrade, replace/redesign mezzanines.

    • Issues;

      • Interconnectivities, Connectors and Plug-in;

      • Need First Prototype and Firmware to verify.
