Arm® CPU Device¶
Introducing the Arm® CPU Plugin¶
The Arm® CPU plugin is developed in order to enable deep neural networks inference on Arm® CPU, using Compute Library as a backend.
This is a community-level add-on to OpenVINO™. Intel® welcomes community participation in the OpenVINO™ ecosystem, technical questions and code contributions on community forums. However, this component has not undergone full release validation or qualification from Intel®, hence no official support is offered.
The set of supported layers and their limitations are defined on the Op-set specification page.
Supported Inference Data Types¶
The Arm® CPU plugin supports the following data types as inference precision of internal primitives:
Floating-point data types:
Quantized data types:
i8 (support is experimental)
Hello Query Device C++ Sample can be used to print out supported data types for all detected devices.
Preprocessing Acceleration The Arm® CPU plugin supports the following accelerated preprocessing operations:
u8 -> u16, s16, s32
u16 -> u8, u32
s16 -> u8, s32
f16 -> f32
Transposition of tensors with dims < 5
Interpolation of 4D tensors with no padding (
The Arm® CPU plugin supports the following preprocessing operations, however they are not accelerated:
Precision conversion that is not mentioned above
NV12 to RGB
NV12 to BGR
i420 to RGB
i420 to BGR
For more details, see the preprocessing API guide.
The plugin supports the properties listed below.
