CPU configuration
Clock Speed
The CPU is constantly fetching and executing instructions and the speed at which it does this is determined by an electronic clock. This clock uses a vibrating crystal maintains a constant speed. Clock speeds are measured in Hertz (Hz), which is the unit of frequency and means 'number of times per second '.
Cache
Cache memory is located between the main memory and the CPU. It is used to hold data that needs to be accessed very quickly. Accessing cache memory is much faster than accessing main memory.
Cores
Another factor that can affect the performance of the CPU is the number of processor cores. Each core can fetch and execute instructions independently so a multiple core processor can handle several instructions at the same time.

Cache Memory Purpose
In personal computers, cache memory is used to speed up access to data and applications. By storing frequently used data in cache, the CPU can access this data much faster than if it had to retrieve it from the main memory or the hard drive.
CPU definitions
The Central Processing Unit (CPU) is the primary component of a computer that acts as its “control center .” The CPU, also referred to as the “central” or “main” processor, is a complex set of electronic circuitry that runs the machine's operating system and apps.
Embedded systems
An embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/output peripheral devices—that has a dedicated function within a larger mechanical or electronic system.
