The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
A modern consumer CPU made by Intel: An Intel Core i9-14900KF Inside a central processing unit: The integrated circuit of Intel's Xeon 3060, first manufactured in 2006. A central processing unit (CPU), also called a central processor, main processor, or just processor, is the most important processor in a given computer.
Mode protection may extend to resources beyond the CPU hardware itself. Hardware registers track the current operating mode of the CPU, but additional virtual-memory registers, page-table entries, and other data may track mode identifiers for other resources. For example, a CPU may be operating in Ring 0 as indicated by a status word in the CPU ...

An opened ATX case, front towards right. Components pictured include a microATX motherboard (top), a CPU (beneath the Cooler Master fan), a GPU (middle), and an SSD (right). The power supply is housed in the compartment at bottom. A computer case, also known as a computer chassis, is the enclosure that contains most of the hardware of a ...
There are several forms of processors specialized for machine learning. These fall under the category of AI accelerators (also known as neural processing units, or NPUs) and include vision processing units (VPUs) and Google's Tensor Processing Unit (TPU). Sound chips and sound cards are used for generating and processing audio.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
