OpenHarmony supports the following system types:

Mini system

For MCU-like processors such as Arm Cortex-M and RISC-V 32-bit devices, the hardware resources are extremely limited. The minimum memory supported by the device is 128KiB, which can provide a variety of lightweight network protocols, lightweight graphics frameworks, and Abundant IOT.

Small system

For application processors such as Arm Cortex-A devices, the minimum memory supported by the device is 1MiB, which can provide higher security capabilities, standard graphics frameworks, and multimedia capabilities for video encoding and decoding.

Standard system

For application processors such as Arm Cortex-A devices, the minimum memory supported by the device is 128MiB, which can provide enhanced interaction capabilities, 3D GPU and hardware synthesis capabilities and more.
