The Center Processing Unit (CPU) is the core component of the mobile phone. The microprocessor in the mobile phone is similar to the central processing unit (CPU) in the computer. It is the control center system of the whole mobile phone and the control core of the logic part. It is the core of the mobile phone, equivalent to the CPU function of the computer. The performance of the processor determines the performance of the entire phone. All the data to be processed must be completed by the CPU, and the management of various parts of the mobile phone cannot be separated from the unified and coordinated command of the microprocessor. With the continuous improvement of integrated circuit production technology and process level, the function of microprocessors in mobile phones is becoming more and more powerful, such as the integration of advanced digital signal processors (DSP) in the microprocessor. ARM(Advanced RISC Machines) can be considered as the name of a company, it can also be considered as a general term for a class of microprocessors, and it can also be considered as the name of a technology. ARM was founded in Cambridge, England, in 1991 to sell licenses to chip design technology. At present, the microprocessor using the intellectual property (IP) core of ARM technology, that is, we usually refer to the ARM microprocessor, has been widely used in industrial control, consumer electronic products, communication systems, network systems, wireless systems and other product markets, microprocessor applications based on ARM technology occupy more than 75% of the market share of 32-bit RISC microprocessor. ARM technology is gradually infiltrating into all aspects of our lives. ARM is a company specializing in the design and development of RISC chip technology. As an intellectual property supplier, it does not directly engage in chip production, but relies on the transfer of design licenses to partner companies to produce distinctive chips. The world's major semiconductor manufacturers purchase ARM microprocessor cores designed by ARM, according to their different application fields. Add the appropriate peripheral circuitry, thus forming your own ARM microprocessor chip into the market. At present, dozens of large semiconductor companies around the world are using ARM's license, so ARM technology not only gets more third-party tools, manufacturing, software support, but also reduces the cost of the entire system, so that products are easier to enter the market and accepted by consumers, more competitive.
