Hi,
Internally we have checked performance of memcpy() and it s expected that Orin has better performance. We don’t check vst1q_u32() and don’t have much experience of using it. It seems to be an experimental function per
vst1q_u32 in core::arch::arm - Rust
If calling memcpy() is fine in your use-case, we would suggest call this function instead of calling vst1q_u32()
