Abstract

Background. Nowadays, methods of digital processing of continuously incoming information at a high frequency are widely used in various fields of science and technology. In many cases the performance of signal processors is not enough, the only option is to implement specialized processors on FPGAs. In scientific literature publications on the subject matter are quite rare, so the subject of the article seems to be quite relevant. The purpose of the study is to develop specialized processors based on FPGA allowing to perform preliminary calculations of characteristics of continuously incoming information at high frequencies and transmission of the results for the final processing to the CPU.
Materials and methods. To ensure high performance of continuously incoming information processing the authors used conveyor calculation methods and methods of digital signal processing
Results. The authors developed a structure of the specialized pipelined processor of FPGA-based digital signal processing for preprocessing and transmission of the results for the final processing to the CPU and experimentally studied the units of the developed processor.
Conclusions. The method for selection of processor nodes parameters, described in the paper, can reducehardware costs. The methods for calculating frequency characteristics allow to determine the characteristics of internal signals and nodes of the processor inside the FPGA, which simplifies the setup of real circuits.

Key words
