It supports two instruction set architecture (ISA):

Thanks to its unique architecture Elbrus 2000 can execute 20 instructions per clock, so even with its modest clock speed it can compete with much faster clocked superscalar microprocessors when running in native VLIW mode.

For security reasons the Elbrus 2000 architecture implements dynamic data type-checking during execution. In order to prevent unauthorized access, each pointer has additional type information that is verified when the associated data is accessed.
