time consuming opencv functions on SDSoC

Hello everyone,

I am trying to accelerate an application on SDSoC 2019.1. However, whenever I call the opencv functions, my performance is lowering. For example, even cv::imread function takes 50ms. Do you know why would it be? I saw the issue below and I tried what is told in the answer. It didn't help.

When I called the function in the link( getBuildInformation() function ) I am seeing the following lines:

Timestamp: 2020-01-28T16:51:00Z
Host: Linux 5.3.0-26-generic x86_64
Target: Linux aarch64
CMake: 3.12.2
CMake generator: Ninja
CMake build tool: ninja
Configuration: Release

CPU/HW features:
Baseline: NEON FP16
required: NEON
disabled: VFPV3

 

Would this be the reason?

 

Thanks for any kinda help.
