What's difference between DLAs and Vision Accelerator?

Hi all,
I know about DLAs in xavier series that can run the deep learning models such as TLT/Tensorflow/Caffe … models.
Q1- But I don’w know about vision Vision Accelerator? What’s this purpose? This HW use for computer vision and image processing algorithm with libs like opencv? Is use for deep learning models?
Q2- What’s mean 7-way VLIW vision processor refer to this accelerator?
Q3- For using this accelerator we had to use specific libs?
Q4- Is there a samples codes for using this accelerator?

hello LoveNvidia,

it’s Programmable Vision Accelerators (PVA) and Deep Learning Accelerators (DLA).
please access Xavier Series SoC Technical Reference Manual via download center.
you might search for PVA and DLA for more details.
thanks

hello LoveNvidia,

besides TRM, you may also check NX SOM Data Sheet for some information.
you might have a try to execute TensorRT to use the DLA engines, by adding useDLACore options into the pipeline; please also check Topic 67031 for reference,
thanks
