  10. Process FlowSimilar to all Units Loading data on board FIFOs from PCI Loading control registers from PCI Transferring data to internal RAMs from external memory Sending Start Loading signal to CTF/DSP/Exp. Units Receiving Ready signal from the CTF/DSP/Exp. Units Sending Ready signal to the main controller. All units ready Main controller Starts the A2D and the system runs

  11. Expander Entity Outputs: ready_to_arch – finished initilization data_to_main – main output to CTF/DSP (20[MHz]) data_to_main_valid – main output is valid data_to_CTF – iteration output (2[MHz]) data_to_CTF_valid – iteration output is valid memory_read_request – request data from memory Inputs: Clk_60 – 60MHz input data clock Clk_20 – 20MHz main output data clock Clk_2 – 2MHz iteration output data clock Clk_240 – 240MHz processing clock From main controller : rst – reset start_load – memory ready for read num_of_itr – number of wanted slice pause – pause the system From CTF : req_pulse – request of new slice Memory (20[MHz]) : memory_data – data from memory memory_ack – requested data is ready From A/D (60[MHz]) : Data_from_AD – input data for the system Data_in_valid – the input is valid

  23. Future Aspirations Studying each group Entity’s I/O and single Debug mode operations (from Dima and Oleg) Studying Board busses, memories and communication clocks phase\skew problem (Gadi’s Project handle it) Design and Implement the communication blocks (Interface blocks) needed for the across linked FPGA’s- and the same time to be able to support groups with 1 FPGA Debug mode operation. Debug entire board+ all group’s Entity’s, we will held continuous meetings with the groups to synchronize with them and update them with the needed architecture changes. (each change they might have need to be informed and confirmed with us) Design and Implement Debug GUI (Visual C? JAVA? LabView?)- creating the test environment Improve GUI for board users

  25. project part B (Not in the Gantt…) • Exams period B…  • Test and Debug Entire Board • Finish GUI Test Environment • Improve GUI to System controlling GUI
