NVDLA Open Source Software
The NVIDIA Deep Learning Accelerator (NVDLA) is a free and open architecture that promotes a standard way to design deep learning inference accelerators. With its modular architecture, NVDLA is scalable, highly configurable, and designed to simplify integration and portability. Learn more about NVDLA on the project web page.
You can find the latest NVDLA SW documentation here. This README file contains only basic information.
Kernel Mode Driver
The kernel mode driver (KMD) is supported as a Linux out-of-tree kernel module. It has been verified with Linux 4.13.3 on ARM64 and is expected to work on other cpu architectures with little or no modification. The driver uses DRM and GEM PRIME for DMA buffer allocation and sharing.
Building the Linux KMD
make KDIR=<path_to_Linux_source> ARCH=arm64 CROSS_COMPILE=<path_to_toolchain>
User Mode Driver and test application
The user mode driver (UMD) includes runtime library. It provides interfaces to load network from loadable and submit it to NVDLA KMD. For reference, this package also includes test application demonstrating usage of runtime interfaces.
Building the Linux UMD and test application
export TOP=<path_to_umd> make
