Elbrus-2S+

The Elbrus-4S CPU uses a VLIW instruction set where it can perform up to 23 instructions per clock cycle and is reported to have support for Intel x86 emulation through a virtual machine. When programs are built for Elbrus 2000 native mode, the compiler determines how the different operations shall be distributed over the 23 computing units before saving the final program. This means that no dynamic scheduling is needed during runtime, thus reducing the amount of work the CPU has to perform every time a program is executed. Because static scheduling only needs to be performed one time when the program is built, more advanced algorithms for finding the optimal distribution of work can be employed. ==Specifications==

The south bridge for the Elbrus 2000 chipset, which connects peripherals and bus to the CPU is developed by MCST. It is also compatible with the MCST-R1000. ==Applications==

In December 2012, Kraftway announced that it will deliver an Elbrus based PC together with its partner MCST. In December 2014, an implementation of the OpenGL 3.3 standard was demonstrated by running the game Doom 3 BFG Edition on an Elbrus-4S, clocked at 720 MHz, using a Radeon graphics card with 2 gigabytes of video memory. In June 2024, the “Elbrus-2S3 (Эльбрус-2С3) microprocessor” 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 September 2024, The MCST company presented “Elbrus-2S3 (Эльбрус-2С3) microprocessor” at the 10th anniversary Russian forum "Microelectronics 2024". ==References==
