Elbrus-4S (rus. Эльбрус-4С, code designation: 1891ВМ8Я) is an universal multi-core VLIW microprocessor with the Elbrus architecture, developed by the russian company MCST.
Overview
The «Elbrus-4S» processor contains 4 cores, level 2 cache memory with a total capacity of 8 megabytes, 3 memory controllers compliant with DDR3-1600, 3 interprocessor communication channels and an input-output channel. Each processor core executes 23 instructions per cycle. The processor contains hardware support for binary translation of 64-bit Intel/AMD codes. The peak processor performance is 25 Gflops for a 64-bit configuration and 50 Gflops for a 32-bit configuration[1]. The average power dissipation is 45 watts. The microprocessor is intended for use in personal computers and servers[2][3].
