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.
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]

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.).
CPU is a computer's central processing unit. CPU may also refer to: Science and technology. Carboxypeptidase B2, a human enzyme; Critical Patch Update, software ...
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).
TIMI is a virtual instruction set independent of the underlying machine instruction set of the CPU. User-mode programs contain both TIMI instructions and the machine instructions of the CPU, thus ensuring hardware independence. This is conceptually somewhat similar to the virtual machine architecture of programming environments such as Java and ...
For example, an IBM PC with an Intel 80486 CPU running at 50 MHz will be about twice as fast (internally only) as one with the same CPU and memory running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors that implement different architectures and microarchitectures ...
