The Android Neural Networks API (NNAPI) is an Android C API designed for running computationally intensive operators for machine learning on mobile devices. Tensorflow Lite is designed to use the NNAPI to perform hardware-accelerated inference operators on supported devices. Based on the app’s requirements and the hardware capabilities on a device, the NNAPI can distribute the computation workload across available on-device processors, including dedicated neural network hardware, graphics processing units (GPUs), and digital signal processors (DSPs). For devices that lack a specialized vendor driver, the NNAPI runtime relies on optimized code to execute requests on the CPU.
