Background/Objectives: The study analyzes methods and techniques for improving the effective speed of computing units to solve the problems of digital processing of broadband signals by introducing special vector instructions. Methods: Uniquely effective methods of digital matched filtering (MF) have been suggested for broadband signal processing: sub-aperture method and the coded moving total method. Findings: Performance evaluation of the matched filtering schemes and algorithms showed that, in a number of MF broadband signal problems, the coded moving total method proved to be 3-20 times more effective than the direct convolution method, and two times more effective than the fast convolution method based on fast Fourier transform (FFT) algorithms; the method of sub-apertures proved to be 2-6 times more effective than the direct convolution method. Applications/Improvements: Two equipment instruction manuals for moving summation in EL-core IP-cores have been developed, improving their effective performance of filtration by several times. The algorithms are used in ORWELL-R (OJSC R&D Center ELVEES) modern security radar station.
