## brief
The multi_device demo uses some acuity exported tim-vx networks, and running on multi-core devices of NPU using platform api.

## note
Please note that if you have enabled lite platform, a dedicated VIVANTE_SDK(NO_KERNEL) is required as the compiler for NBG.
The driver for the NPU is the VIPLITE driver

##requirements
Vivante SDK >= 6.4.22
ovxlib >= 1.2.26
viplite >=2.0.0

## build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DTIM_VX_USE_EXTERNAL_OVXLIB=ON -DEXTERNAL_VIV_SDK=${VIVANTE_NOKERNEL_SDK_DIR} -DOVXLIB_INC=${OVXLIB_DIR}/include \

## environment
# Export VIV_GPU_FILE to specify the NPU hardware configuration file for the NBG compiler
# VIV_GPU_FILE Specify the NPU hardware configuration file for the NBG compiler
