hi,

but i dont think we build UDMA library for A72 in PDK.

Why do you want to use UDMA on A72? Its not accessible in the A72 application space.

Hi, Brijesh

we want to accelerate the process of memcpy from HOST input address to target vx_tensor， we map target vx_tensor through

tivxMapTensorPatch, and then memcpy from HOST input to the mapped vx_tensor address. How can I accelerate this process.

Hi,

Unfortunately, UDMA is not available on Linux user space. You would probably have to use R5F or C7x to do this memory copy.
