Here is more information from official site [1,4,5]:
- native "Elbrus" ISA or x86 ISA,
- Ebrus ISA is VLIW, can dispatch 23 operations per cycle (33 with SIMD), in-order execution,
- it's stated that x86 code translation + register allocation is done in HW, but later they write about a software translator and full-system emulator,
- 6 ALUs (all support integer operations, 4 can do FP),
- 256 x 84-bit register file,
- hardware support for loops, including pipelining,
- some kind of module for async mem preloading,
- speculative execution and branching predicates,
- "4S" model has 4 cores,
- 800 Mhz core clock,
- 64 KB L1, 128 KB L2, 8 MB L3 (shared between cores),
- 3 DDR3-1600 interfaces, ECC support,
- 3 x 12GBytes/s inter-CPU links, support for up to 4 sockets,
- 65nm process, 380 mm^2 die size, 986e6 transistors,
- software is based on Linux 2.6.33 and Debian 5.0 with more than 3000 packages.
There are some benchmarks for older chip model "2S" (overclocked to 500MHz, 2 cores) [2,3]. FP performance is about 1-5x of Pentium M 1GHz (1 core?) depending on benchmark, integer performance is about 1x. New CPU, "4S", should be 3 times faster than "2S".
