Description

Technical field [0001] The present invention is a minimum system structure design of a 32-bit embedded microprocessor, and relates to the technical field of microprocessor application, in particular to a minimum system structure design based on a 32-bit ARM embedded microprocessor. Background technique [0002] With the application and promotion of embedded technology, as the core of embedded systems, embedded microprocessors have gradually transitioned from 8-bit and 16-bit to 32-bit. In the field of 32-bit embedded microprocessors, it is based on high performance, low cost, Embedded microprocessors with low power consumption and small size ARM core account for more than 75% of the market share and have achieved great success in the field of 32-bit embedded applications. [0003] However, compared with embedded applications using 8 / 16-bit microprocessors, application systems based on 32-bit ARM embedded microprocessors have greatly improved in terms of system structure, developm...
