Keynote

The flexibility, cost effectiveness, performance efficiency and reconfigurability enable FPGAs to be in par with the challeges propelled in the modern digital signal processing chains especially in tackling systems with huge data throughput. One such system is Metallic Magnetic Calorimeters (MMCs), which have gained much attraction during the last two decades to meet the rapidly increasing demand of highly sensitive energy dispersive detectors. Their high spectral resolution at wide bandwidths in the range of GHz calls for specialized hardware solutions in ASICs or FPGAs. Channelization of these frequency multiplexed signals is a very critical issue since the operating frequency of FPGAs is limited to a few hundred MHz and thereby the urgency to exploit the inherent parallelism property of FPGAs is highly essential. In particular, emphasis is placed on efficient optimized DSP techniques based on

  • Poly-phase filter banks
  • Pipelined-parallelized FFTs or
  • Optimized time domain approaches.

This Master thesis tends to design one of the aforementioned techniques for achieving high-speed channelization without degrading the spectral resolution.
