Execution unit

As an integrator or plant operation is referred to in microelectronics and computer science technical a switching mechanism for executing the machine instructions of a computer program. The term is often used synonymously with arithmetic logic unit (ALU ), but strictly speaking, represents an ALU, only the central component of an arithmetic unit is that additionally consists of a number of auxiliary and status registers. In addition, an arithmetic logic unit also contain several ALUs. Example, there are floating-point arithmetic units in addition to the register sets of two ALUs for separate manipulation of the exponent and mantissa of a floating point number. The ALU itself, however, does not register cells and thus represents a pure switching power dar. Modern high-performance computers have a number of arithmetic units that operate independently of each other and are each specialized in the execution of special commands.
