CPU: The smaller, the bigger

The 'heart' of every computer is the CPU. This Central Processing Unit (CPU) is a miniaturized computing chip that processes defined computing processes ('algorithms') according to its 'architecture' of semiconductors (or 'transistors'). CPUs are no longer only found in computers, but nowadays also in washing machines, cars and ticket machines, for example.

A CPU consists of several components. The arithmetic-logic unit (ALU) forms the center. It is supplemented by the control unit, which primarily manages addresses. Registers and a memory manager (Memory Management Unit or MMU) complete the core of the chip.

Small 'helpers' - or co-processors - support the central processing unit in its tasks, for example by performing floating point operations. Today's CPUs are designed as multi-core units, which increases parallel processing and the speed at which tasks are solved. The data lines ('buses') ensure communication with the other components of the computing system, especially with the main memory. 'Caches' (intermediate memory) enable rapid further processing of partial results.

The choice of processors used in a company should be based on the tasks to be performed. The most expensive solution is by no means always the best or most efficient. Just ask us ...
