The Central Processing Unit (CPU) or processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. This term has been in use in the computer industry at least since the early 1960s (Weik 2007). The form, design and implementation of CPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same.
At the heart of all personal computers and workstations sits a microprocessor. Microprocessors control the logic of almost all digital devices, from clock radios to fuel-injection systems for automobiles. It is also responsible for all the mathematical calculations performed during the execution of any program.
Three basic characteristics differentiate microprocessors:
Technically, a microprocessor is a kind a CPU.
A CPU or Central Processing Unit is generally what is meant by the term microprocessor. Sometimes microprocessor can refer to additional hardware, but by and large, CPU = microprocessor.

The best answer is, it depends on the computer architecture. In a personal computer, CPU and microprocessor are one and the same. In a larger computer such as an AS400, the CPU is a separate unit with lots of microprocessors and other chips. The larger the computer system, the more spread out the CPU functions are among components.Another AnswerThe CPU (Central Processing Unit) is the core of any computer, while the microprocessor refers to the whole functional chip that is inserted into a motherboard. The CPU is the sub architecture of the microprocessor that interprets the program instructions and cascade triggers the sub-functions of each instruction.
No. While a CPU is an example of a microprocessor, many microprocessors are not CPUs, but perform other tasks to aid the CPU. An example would be the GPU of a video card, or the DSP (Digital signal processor) of a modem or sound card.
