== Translating control units == Some computers translate each single instruction into a sequence of simpler instructions. The advantage is that an out of order computer can be simpler in the bulk of its logic, while handling complex multi-step instructions. [[x86]] Intel CPUs since the [[Pentium Pro]] translate complex CISC x86 instructions to more RISC-like internal micro-operations. In these, the "front" of the control unit manages the translation of instructions. Operands are not translated. The "back" of the CU is an out-of-order CPU that issues the micro-operations and operands to the execution units and data paths.
