Title
Asynchronous-QDI 2D IIR digital filter circuits
Abstract
This paper investigates the potential of emerging asynchronous quasi delay insensitive (a-QDI) logic devices for the realization of high-speed low-power 2D infinite impulse response digital beam filters. Recently proposed raster-scanned hardware architectures based on direct-form I and wave-digital realization are extended to clock-free asynchronous logic using state-of-the-art asynchronous field programmable gate arrays from Achronix Semiconductor. For the specific class of 2D IIR beam filters based on raster-scanned hardware, it is shown using extensive experimental work that direct-form I architectures greatly benefit from the adoption of a-QDI logic over standard clocked (synchronous) digital circuits while wave-digital filters show no difference in performance. To the author's knowledge, the proposed 2D IIR hardware circuits are currently the only available realization of 2D IIR filters in the literature based on the new clock-free a-QDI paradigm.
