HyperSpeed

HyperSpeed is an exceptionally fast FFT core. It is ideal for applications where both high processing speed and efficient FPGA resource usage are critical. Using an advanced parallel pipelined architecture, HyperSpeed can process data continuously in real time at rates of over 100 Gsps. Its highly configurable design features scalable transform length and processing parallelism and can be tailored to any one of a huge field of applications. HyperSpeed offers both the flexibility and performance demanded for a new generation of high performance signal processing tasks.

Features

  • A fixed sample rate of between 3.6 Gsps and over 52 Gsps for real-valued data (equivalent to between 1.8 Gsps and 26 Gsps for complex data)
  • Complex parallelisms of between 4 and 256 (factory setting)
  • Dynamic selection of FFT or IFFT transform
  • Continuous real-time data processing at > 100 Gsps
  • A wide range of choices for processing parallelism, selected at build-time
  • FFT length up to 128k-points, with larger transforms available subject to parallelism and FPGA resource requirements
  • Factory-adjustable precision and scaling
  • Flexibility in balancing usage of different FPGA resources
  • A choise of data format and ordering options
