Elbrus (computer)
Template:Short description Template:More footnotes
The Elbrus (Template:Langx) is a line of Soviet and Russian computer systems developed by the Lebedev Institute of Precision Mechanics and Computer Engineering. These computers are used in the space program, nuclear weapons research, and defense systems, as well as for theoretical and researching purposes, such as an experimental Refal and CLU translators.
HistoryEdit
Historically, computers under the Elbrus brand comprised several different instruction set architectures (ISAs).
The first of them was the line of the large fourth-generation computers, developed by Vsevolod Burtsev. These were heavily influenced by the Burroughs large systems and similarly to them implemented tagged architecture and a variant of ALGOL-68 as system programming language.
After that Burtsev retired, and new Lebedev's chief developer, Boris Babayan, introduced the completely new system architecture. Differing completely from the architecture of both Elbrus 1 and Elbrus 2, it employed a very long instruction word (VLIW) approach.
In 1992, a spin-off company Moscow Center of SPARC Technologies (MCST) was created and continued development, using the "Elbrus" moniker as a brand for all computer systems developed by the company.
In the late 1990s, a series of SPARC-based central processing units (CPUs) were developed at MCST as a way to raise funds for in-house semiconductor intellectual property core development and to fill the niche of domestically-developed CPUs for the backdoor-wary military.
In June 2024, a new computer based on the “Elbrus-2S3 (Эльбрус-2С3) microprocessor”<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> was developed by Roselektronika.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
In September 2024, The MCST company presented “Elbrus-2S3 (Эльбрус-2С3) microprocessor”<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> at the 10th anniversary Russian forum "Microelectronics 2024".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
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.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }} - The MP21 module based on the Elbrus-2S3 processor is implemented in the Com Express Type 6 Compact form factor (95×95 mm). The module is a "computer on a module" - an embedded industrial module manufactured in accordance with the international standard for use as a mezzanine installed on specialized carrier boards. Recommended retail price RUB 245,700 (without VAT).</ref>
