CPU cores comprise multiple subunits, including ALUs (arithmetic logic units) and FPUs (floating point units). In this block diagram of the AMD Zen 5 desktop version below, you can trace the flow of information from the "frontend," which includes the control unit, through ALUs into the L1...

A processor (CPU) is the logic circuitry that responds to and processes the basicinstructionsthat drive a computer. The CPU is seen as the main and most crucial integrated circuitry (IC)chipin a computer, as it is responsible for interpreting most of computers commands. CPUs will perform most...
The instruction controller is a very important part of the controller. It must complete the operations such as fetching instructions and analyzing instructions and then hand it over to the execution unit (ALU or FPU) for execution. At the same time, it also forms the address of the next inst...
While processorarchitecturesdiffer between models, each processor within a CPU typically has its ownALU,FPU,register, and L1cache. In some cases, individual processing cores may have their own L2 cache, though they can also share the same L2 cache. A singlefrontside busroutes data between the ...

In a sense it can be part of the CPU since it can be implemented as a microprogram within the CPU. In such case, the CPU now does all the functions of an FPU but this is less efficient than a dedicated FPU since this would take up valuable CPU time that could have been used to ...
Central processing unit (CPU):Colloquially referred to as the computer’s “brain,” the CPU is responsible for executing instructions and controlling operations. Memory:Microcontrollers contain both volatile memory (RAM), which stores temporary data that may be lost if the system loses power, and ...
Maybe the CPU is too slow, or there’s no direct memory access, or there is very little hardware support for mathematical operations. But we could also think about microcontrollers in terms of what they have rather than what they lack. In this view, applying the category “microco...
