Evolution of modern microprocessors architecture

Preconditions of the first microprocessors with CISC architecture development are considered. Its shortages, partially connected with its redundancy, are discussed. The development of RISC architecture microprocessors as an alternative to CISC is considered. It is pointed that both architectures apply dynamical control of instructions execution. Static method of control is used in VLIW architectures, which features are also described. In such case, the main part of the control process is performed by compilers.
