Analysis of using a MicroBlaze processor for hardwareimplementation of algorithms for data processing in electronic recognition devices and systems based on the example of a XILINX FPGA system

摘要

In contemporary devices, reconnaissance systems, and radio-electronic warfare there is a necessity to process very largeamounts of measurement data in real time. For this purpose, the possibility of hardware implementation for various typesof algorithms in FPGA (Field-Programmable Gate Array) is of great importance. With the intensive development ofsemiconductor technology observed in the recent years, programmable devices have undergone very significant changesin recent years. A notable increase in logical resources has enabled implementation of a programmable processor core inthe FPGA. This paper presents an example of the system which is capable of processing measurement data obtainedfrom a radar as well as control data required for controlling the processing circuit which has been implemented inMicroBlaze processor. The MicroBlaze processor is a soft processor designed for the effective implementation withinprogrammable systems. In this paper two solutions based on the Xilkernel real time system (a solution based on Linux)and the Xilinx Standalone version have been discussed. The proposed solutions may be the basis for building efficientdata processing components in electronic warfare (EW) devices. Performance tests of the individual solutions have beenmade on the basis of signals received from the FMCW (Frequency-Modulated Continuous-Wave) radar.
