- ### System type
- Mini system: a system running on the devices that come with MCU processors, such as Arm Cortex-M and 32-bit RISC-V, and memory greater than or equal to 128 KiB. This system provides rich short-distance connection capabilities and a bus for accessing peripherals. This system applies to smart home products such as LinkIoT module devices and sensors.
- Small system: a system running on the devices that come with application processors such as Arm Cortex-A and memory greater than or equal to 1 MiB. This system provides higher security capabilities, standard graphics frameworks, and video encoding and decoding capabilities. This system applies to smart home products such as IP cameras, peephole cameras, and routers as well as smart travel products such as event data recorders (EDRs).
- Standard system: a system running on the devices that come with application processors such as Arm Cortex-A and memory greater than or equal to 128 MiB. This system provides a complete application framework supporting the enhanced interaction, 3D GPU, hardware composer, diverse components, and rich animations. This system applies to high-end refrigerator displays.
