MCST (Moscow Center of SPARC Technologies, Russian: закрытое акционерное общество (ЗАО) «МЦСТ») is a microprocessor company that was set up in the 1992s. Different types of processors made by MCST were used in personal computers, servers and computing systems.

MCST develops microprocessors based on 2 different instruction set architecture (ISA): Elbrus and SPARC

Elbrus 1 (1973) was the fourth generation Soviet computer, developed by Vsevolod Burtsev. Implements tag-based architecture and ALGOL as system language like the Burroughs large systems. A side development was an update of the 1965 BESM-6 as Elbrus-1K2.
Elbrus 2 (1977) was a 10-processor computer, considered the first Soviet supercomputer, with superscalar RISC processors. Re-implementation of the Elbrus 1 architecture with faster ECL chips.
Elbrus 3 (1986) was a 16-processor computer developed by Boris Babaian. Differing completely from the architecture of both Elbrus 1 and Elbrus 2, it employed a VLIW architecture.
Elbrus-90micro (1998-2010) is a computer line based on SPARC instruction set architecture (ISA) microprocessors: MCST R80, R150, R500, R500S and MCST-4R working at 80, 150, 500 and 1000 MHz.
Elbrus-3M1 (2005) is a 2-processor computer based on Elbrus 2000 microprocessor employing VLIW architecture working at 300 MHz. It is a further development of the Elbrus 3 (1986).
Elbrus МВ3S1/C (2009) is a ccNUMA 4-processor computer based on Elbrus-S microprocessor working at 500 MHz.
Elbrus-2S+ (2011) is a dual-core Elbrus 2000 based microprocessor working at 500Mhz, with capacity to calculate 16GFlops.
Elbrus-2SM (2014) is a dual-core Elbrus 2000 based microprocessor working at 300Mhz, with capacity to calculate 9.6GFlops.
Elbrus-4S (2014) is a quad-core Elbrus 2000 based microprocessor working at 800Mhz, with capacity to calculate 50GFlops.
Elbrus-8S (2014-2015) is a octa-core Elbrus 2000 based microprocessor working at 1300Mhz, with capacity to calculate >200GFlops.
