MPU refers to the microprocessor unit, is an integrated circuit chip, mainly used to control and process the data and instructions of the computer system. Common MPU chips include Intel's x86 series, ARM's Cortex series, and AMD's Ryzen series. These chips have the characteristics of high performance, low power consumption and strong programmability, and are widely used in personal computers, servers, smart phones, tablets, Internet of things and other fields. The development of MPU chips not only promotes the progress of computer technology, but also brings more convenience and innovation to people's lives.
MPU has two meanings, microprocessor and memory protection unit. The MPU is a single chip, and the chipset is composed of a group of chips, even as many as 7 or 8 in the early days, but most of them are now combined into 2, generally called North Bridge chip and South Bridge chip. The MPU is the computing, judgment, or control center of the computer, and some people call it the \"heart of the computer.\"
