  2. ROD Overview

  3. ROD, TIM and BOC Overview TIM (Timing Interface Module) Receives clock and trigger information from the TTC Transmits clock and trigger information to the ROD Receives busy information from the ROD Masks and passes on busy to the L1 Trigger Operates stand alone under control of the RCC RCC (ROD Crate controller) Reads configuration data from the ATLAS data base Configures the TIM, ROD and BOC Controls the operation of the crate Monitors the crate during running Provides control and configuration in stand alone mode

  4. ROD, TIM and BOC Overview BOC (Back of Crate Card) (ROD optical fiber interface) Receives optical module data and formats data for the ROD input Receives module control data from ROD and formats data for the optical fibers Provides individual fiber delays Houses the Slink interface ROD (Read Out Driver) Formats input data Provides latency FIFOs Corrects header and trailer errors Corrects header and trailer Counts errors Provides for calibration of modules Traps and monitors event data Formats data for Slink input

  8. ROD Overview Changes or major events since the last review 1. The formatter has been changed to increase the link to link latency from one to two clock tick. The resultant Formatter is more robust. The through rate is still determined by the the s-link. 2. The Router trapping of events for the DSP is more flexible. Based on event types with pre scale. 3. Controller FPGA code has been upgraded to have L1ID and BCID counter internal for self triggering of the ROD. 4. DSP software has been written to allow configuration and triggering of front end modules.

  9. ROD Overview Changes or major events since the last review 5. Four production model boards have been fabricated and debugged. So far they will be production RODs. 6. The number of back end DSPs loaded on the ROD has been changed from two to four. 7. DSP software has been written to allow histogramning of modules. (early version) 8. The data path has processed events at 100kHz. 9. Front end modules have been configure. 10. Event data has been readout over VME. 11. Histograms of calibration data has been made in the slave DSPs and read out over VME.
