instruction level parallelism (superscalar) (ILP)

Instruction Level Parallelism (ILP) is instruction level parallel processing. This technique allows processors to execute multiple independent instructions simultaneously.

The advantage of these processors is that they contribute to an enormous increase in processor performance, comparable to that of multiprocessor systems, and, as superscalar processors, they can execute programs originally written for sequential processing.

In terms of structure, a processor with parallel processing consists of several parallel execution units in which the individual instructions are executed. Each of these execution units receives its instructions from instruction logic and reads its operations from a central register, to which it also writes its results. The results can be read by all execution units and used for further operations.
