cpu与gpu的作用和位置分析（Role and position analysis of CPU and GPU） The effect of CPU: CPU as the core of a computer, it proved to be irreplaceable, this is the past, today is still such, the future should be like this, but may be increased and endowed with more complex function. Why is CPU able to control the core of a computer and manage a complex and sophisticated computer system with ease? Why can CPU be properly termed brain of computers rather than other components? This is because CPU is designed primarily for the execution of operating systems, system software, scheduling and running a wide variety of applications, and for coordinating and controlling the entire computer system. CPU has a universal characteristic, which is man or generalist, what should be, but this doesnt mean that CPU each task has a top level. The integration of millions, tens of millions or even hundreds of millions of transistors, CPU chip, in addition to computing power circuit and structure, also has a central controller and the other hardware circuit with the circuit structure and modern CPU also has more thinking ability, such as logic, speculative execution, prediction of execution and so on. Only with these qualities will CPU be able to work as a brain for computers. So what does CPU rely on for thought, command, and control? The answer is the instruction set. Instruction set is the set of all CPU instruction processing, no instruction set chip could not be called CPU, but that is the CPU instruction set thinking language, CPU is the smart, it is also a basic attribute different from other chips. Similar to the human brain, involved in the thinking process of any mans language, Chinese with Chinese thinking, Americans English thinking, if used to speak dialect, dialect people even think, people in the subconscious instinct or conditions are most familiar with their own language thinking. The instruction set is the brain CPU language of the computer, and the CPU uses the instruction set to
