Evolution of Spectrometry Systems: A Roadmap to Advanced Data Processing

This overview explores the journey from early spectrometry systems to the latest advancements and future projections. It delves into key milestones such as the POCS and MOPS systems, bandwidth growth trends, and reasons for the technology evolution. Witness the transformation from Xfilt (1994) and DAS (1997) to the latest MOPS Z2X system in October 2005, paving the way for the upcoming CABB system in April 2006. Understand the role of FPGA technology and the significant improvements in design tools that have fueled this evolution. Welcome to the future of spectrometry systems.

  1. The Road to CABB via POCS and MOPS

  2. Overview • Early Systems • Latest System • Future Systems • Bandwidth Growth Trend • Reasons for this Trend

  3. Xfilt (1994) 16MHz 8 Bit Data 2 Polarizations 1 ASIC + 2 FPGAs DAS (1997) 64MHz 8 Bit Data 2 Polarizations 19 FPGAs + ASICs Early Systems

  4. Early Systems Proof Of Concept Spectrometer (POCS) • Designed on a proprietary development board • Four major design revisions

  5. POCS64 (January 2004) 64MHz, 128 Channels 8 Bit Data 1 Polarization 3 VirtexII FPGAs Not installed at Mopra POCS256 (April 2004) 256MHz, 1024 Channels 8 Bit Data 2 Polarizations Installed 3 VirtexII FPGAs Early Systems

  6. POCS256 (April 2004) 256MHz, 1024 Channels 2 Bit Data 2 Polarizations 3 VirtexII FPGAs Installed POCS600 (August 2005) 600MHz, 1024 Channels 2 Bit Data 2 Polarizations 5 VirtexII FPGAs Installed Early Systems

  7. Latest System • MOPS Z2X (October 2005) • 2200MHz, 2 Zoom Bands each of 137.5MHz and 4096 Channels • 2 Bit Data • 2 Polarizations • 5 VirtexIIPro FPGAs • Installed • 1 Terabit per second of data capable of being transferred between chips • Over 300 Billion 18 bit multiplications possible per second

  8. Latest System User has the choice of two separations between the zoom modes

  9. Latest System Results - Spectra C34S CS

  10. Latest System Results – On The Fly Mapping

  11. Future Systems • MOPS (April 2006) • 8GHz Spectrometer • 4 MOPS Z2X Boards with all zoom modes available • CABB • 2GHz Correlator • 8 Bit Data • 32 revised MOPS boards

  12. Bandwidth Growth Trend

  13. Reasons for the Trend • ASICs largely replaced by FPGAs • Major leap in technology • FPGAs are around 4 orders of magnitude larger than they were a decade ago • FPGAs have more dedicated resources • Major improvement in design tools • Simulation throughout development cycle • New debug techniques

  14. Reasons for Trend Development Tools

  15. The End of the Road
