In this tutorial:
You worked to optimize C/C++ code in the Vitis HLS tool, to synthesize it into RTL code for use in the Vitis application acceleration development flow.
With the code optimized, you exported the compiled kernel object (
.xo) file for use in a Vitis application project.
These are the elements of building and accelerating applications and functions using the Vitis and Vitis HLS tools. You can mix the Vitis HLS kernels with RTL kernel objects (.xo) and uncompiled C/C++ kernel code (.c/.cpp) in the Vitis application project to create more complex accelerated applications.
You have the optimized but uncompiled C++ code (dct.cpp) that you saved in an earlier step of this tutorial. You can remove the HLS kernel object and add this optimized C++ code in the Vitis application project if you prefer. In this case, the Vitis IDE will call Vitis HLS as part of the build process when compiling the C++ kernel code.
