abstract

  • An asynchronous implementation of spatially-bandpass 2D IIR frequency-planar digital filter is investigated for obtaining high-speed and low-power digital filter circuits compared to the synchronous implementations. The reduced power consumption and higher speed of operation of the asynchronous architecture has emerging applications in radio-astronomy, space science, radar, and wireless communications. The direct-form-I realization of a 2 nd-order spatially-bandpass 2D IIR filter is extended to a clock-free asynchronous implementation using asynchronous FPGAs from Achronix Semiconductor. The experimental results presented here show that the speed of operation of the asynchronous implementation of the spatially-bandpass 2D IIR filter, in direct-form-I, is 31% higher than its synchronous counterpart, for a look-ahead of 4th-order. © 2011 IEEE.
