FX: A CMOS-Implemented Digital Spectro-Correlator System for Radio Astronomy

A special purpose digital spectro-correlator system, FX, has been developed to perform the real time digital signal processing for the five-element synthesis telescope at the Nobeyama Radio Observatory of Tokyo Astronomical Observatory[Chikada etal.,1983]. This paper outlines the algorithms, architecture and implementation of the FX system. The test and maintenance of the system is also described. This paper is a revised version of an invited paper to the 4th Australian Microelectronics Conference, “Migrating Systems to Silicon”, held in Sidney, 13–15 May, 1985, sponsored by the Institution of Radio and Electronics Engineeres Australia.
