Computational accelerators for analog-to-digital and digital processing of sensor signals in information measuring systems

摘要

The analysis of hardware, temporal and structural complexity of the special processor components, analog-to-digital and digital processing of sensor signals has been carried out. New circuit solutions of analog-to-digital parallel-type converters, single-digit half and full adders, multi-digit combinational and pyramid adders with accelerated transfers, and devices for binary digits sorting and the Hamming distance calculating between signals were proposed. Calculations, diagrams and graphs of estimation of time, hardware and structural complexity of the proposed circuit solutions of computational accelerators were presented. Examples of increasing of the efficiency of the special processor components in comparison with the available ones were shown. A wide scope of application of the developed accelerators in information measuring and image recognition systems was defined.
