Description

technical field

[0001] The invention relates to an SOC circuit based on an 8-bit MCU as the core and a control method for a system using the circuit. Background technique

[0002] With the development of embedded systems and the development of System On Chip (SOC) level products, embedded operating systems are more widely used. However, in the field of consumer electronics, market competition is becoming more and more fierce, and the pressure on product costs is increasing. In the development process of SOC-level products, the application of embedded operating systems needs to provide hardware system support, especially memory and system Support for installation space. In addition, the embedded operating system is mostly used for a central processing unit (Central Processing Unit, CPU) with more than 16 bits. In some fields with fierce market competition, in order to save costs, an 8-bit microcontroller (Mircro-ControlUnit, MCU) is used, and less program space is used, tha...
