Dos PVA support FFT?

“Jetson AGX Orin modules bring support for our next generation Programmable Vision Accelerator
engine, PVA v2. The PVA engine includes dual 7-way VLIW (Very Long Instruction Word) vector
processing units, dual DMA engines, and a Cortex-R5 subsystem. The PVA enables support for various
computer vision kernels such as filtering, warping, image pyramid, feature detection, and FFT. Some
common computer vision applications using the PVA include feature detector, feature tracker, object
tracker, stereo disparity, and visual perception.”
from this description PVA supports FFT but from VPI3.2doc:
VPI - Vision Programming Interface: Algorithms PVA dos not support FFT.

so confused，PVA support FFT or not.

Hi

It means the PVA hardware has the capability to do FFT.
But VPI (software) doesn’t enable it yet.

Thanks.

4

Thanks for reply,
how to do FFT on PVA currently for developers,
any demo can be showed.

Hi,

PVA needs to be launched via VPI.
However, we don’t support FFT (VPI) with PVA right now.

Alternatives, you can try our CPU or CUDA FFT with VPI instead:

Thanks.

6

thanks, can user custom code run on PVA?

7

Hi,

Unfortunately, no.
On Jetson, you will need to use VPI to launch tasks on PVA.

Thanks.

8

Thanks, does DRIVEWORKS also not support user custom code on PVA?

Hi,

Do you use the DRIVE platform?
Please note that the above info is all based on the Jetson device.

Please file a new topic on the DRIVE board if you want to know the info on DRIVE system.

Thanks.

OK thanks very much
