MCST is a Russian microprocessor company that was set up in 1992. Different types of processors made by MCST were used in personal computers, servers and computing systems. MCST develops microprocessors based on two different instruction set architecture (ISA): Elbrus and SPARC. MCST is a direct descendant of the Lebedev Institute of Precision Mechanics and Computer Engineering.
MCST is the base organization of the Department of Informatics and Computer Engineering of the Moscow Institute of Physics and Technology.
MCST develops the Elbrus processor architecture and the eponymous family of universal VLIW microprocessors based on it with the participation of INEUM [ru]. The name "Elbrus" has been given the backronym "ExpLicit Basic Resources Utilization Scheduling".
In June 2024, the "Elbrus-2S3" has resurfaced on the Russian market. This is a nona-core("CPU-core×2" + "3D・GPU-core×1" + "2D・GPU-core×2" + "VPU-core×4") CPU manufactured with a 16nm process. This is the cut down version of the 16-core Elbrus-16S, which might also resurface at some point if there's enough market demand for this to make sense.
In December 2024, Programmable logic controllers "PLC-Elbrus (based on the Elbrus-2S3 microprocessor) " of the holding company "Rostec Electronics" of the State Corporation Rostec have passed state registration and are included in the register of software and hardware complexes of the Ministry of Digital Development of the Russian Federation. This allows using the devices at critical information infrastructure facilities to create automated process control systems.
