Viktor Vladimirovich Prschijalkowski

Viktor Vladimirovich Prschijalkovsky ( Russian Виктор Владимирович Пржиялковский , English transcription Viktor Vladimirovich Przhijalkovskiy ; born March 2, 1930 in Serpukhov , Russian SFSR , Soviet Union ; † . August 23, 2016 in Moscow , Russia , Soviet Union ) was a Russian computer engineer

Life

Prschijalkowski studied at the Moscow Institute for Electrical Engineering, graduating in 1953. After that, he worked at the special design office SDB 245 in its branch Penza , where the first Ural computers were built under the direction of Bashir Ramejew . Prschijalkowski first worked on a special computer for modeling oil deposits and then on the special computer granite for the evaluation of ballistic tests (artillery). 1956 to 1959 he worked on the ALU of a new semiconductor computer in a research center in Noginsk near Moscow.

In 1959 he moved to Minsk , where he worked under Georgi Pawlowitsch Lopato at the Special Design Office (SDB, named after G. Ordzhonikidze) on the new computers of the Minsk series. He was the main designer of Minsk-2, which was already completely transistorized and went into production in 1962. He and his successor Minsk-22 were the first mass-produced Soviet semiconductor-based computers (925 of them were built).

In 1964 he became chief engineer and designed and built the computers Minsk-23, Minsk-32 and then the ES-1020 of the ES series. The Minsk-23 was planned for business applications and came out in 1966. It had advanced features such as instructions with variable word length, protected memory , multitasking . In 1968 the draft of the very popular successor Minsk-32 was finished, of which almost 3,000 pieces were produced. For these 2nd generation Minsk computers (which at that time accounted for up to 70% of the Soviet production of universally usable computers) he and the entire design team received the Soviet State Prize in 1970.

In 1968 a large-scale program for future computer production in the Soviet Union (outside the military-industrial complex) was decided, the ES line of 3rd generation computers compatible with the IBM mainframes ( System / 360 and successors). The production in Minsk was also subordinated to it and the SDB was an offshoot of the Moscow SRIDEC. Prschijalkowski developed the ES-1020, a smaller computer in the series, whose production began in 1971. A total of 756 copies were built, 100 of them in Bulgaria.

Prschijalkowski became scientific deputy director at SRIDEC for the ES computers (he led the design of the ES-1050, which was produced in Penza) and also chief designer of the Argon series of computers used in space travel (Argon 15, 16). He was also involved in the MSM project, the early warning system for ballistic missile defense. He was head of the International Council for ES Development and was involved in it until 1990 - the third series ES-3 followed in 1985 and the fourth ES-4 in the early 1990s.

In 1969 he received his doctorate in Novocherkassk (candidate title) and in 1983 he completed his habilitation (Russian doctorate). In 1985 he received a professorship. In 1983 he became a Hero of Socialist Labor , in 1977 he was awarded the Order of the October Revolution , 1983 the Order of Lenin and in 1971 the Red Labor Banner. He published over 100 scientific papers, including four monographs on the Minsk and ES computers.
