Elbrus-2S+ (Russian: Эльбрус-2С+) is a multi-core microprocessor based on the Elbrus 2000 architecture developed by Moscow Center of SPARC Technologies (MCST). There are multiple reports regarding the evolution of this technology for the purpose of import substitution in Russia, which was raised by several ministries in July 2014, due to economic sanctions in response to 2014 pro-Russian unrest in Ukraine. In December 2014, it was announced that Mikron Group started pilot production of a dual-core variant of this microprocessor called Elbrus-2SM (Russian: Эльбрус-2СМ) using a 90 nanometer CMOS manufacturing process in Zelenograd, Russia.
