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 primary processor in a given computer.
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.).

Apple M1 system on a chip A system on a chip from Broadcom in a Raspberry Pi. A system on a chip or system-on-chip (SoC / ˌ ˈ ɛ s oʊ s iː /; pl. SoCs / ˌ ˈ ɛ s oʊ s iː z /) is an integrated circuit that integrates most or all components of a computer or electronic system.
In computing and computer science, a processor or processing unit is an electrical component (digital circuit) that performs operations on an external data source, usually memory or some other data stream. [1]
In computer architecture, a control bus is part of the system bus and is used by CPUs for communicating with other devices within the computer. While the address bus carries the information about the device with which the CPU is communicating and the data bus carries the actual data being processed, the control bus carries commands from the CPU and returns status signals from the devices.
The term came into use by Intel Corporation about the time the Pentium Pro and Pentium II products were announced, in the 1990s. "Front side" refers to the external interface from the processor to the rest of the computer system, as opposed to the back side, where the back-side bus connects the cache (and potentially other CPUs).
In a hotly-contested marketplace AMD and others released new versions of multi-core CPU's, AMD's SMP enabled Athlon MP CPU's from the AthlonXP line in 2001, Sun released the Niagara and Niagara 2 with eight-cores, AMD's Athlon X2 was released in June 2007. The companies were engaged in a never-ending race for speed, indeed more demanding ...
