Rechenkern
Rechenkern is a German term used in computer science and electronics to denote the central computation unit of a processor, subsystem, or device. It refers to the hardware and, in some cases, the software abstraction that performs numeric processing, i.e., the arithmetic and data-processing operations required to execute instructions. The Rechenkern is typically associated with the arithmetic logic unit (ALU), the floating-point unit (FPU), registers, and the data paths that connect these components with memory and I/O.
In practice, the Rechenkern can take several forms. It may be a fixed part of a CPU,
Usage of the term varies with context, but it generally emphasizes the part of a system responsible
