How to use intrinsics in DM8168

echo yang
Intellectual 730 points

Hello.

I am working with DM8168 and EZSDK5.05. And now I am not using CCS.

I added video scale funtion to the videnc codec.But I cannot use intrinsics to do optimization on C674x.

eg:

If I add "#include <mathf.h>" to the file and add "$(DSP_DEVKIT_PATH)/cgt6x_7_3_1/include" to the XDC_PATH, when compile the example, it says error when building "videnc_copy.ov5T".

I know the arm cannot access the mathf.h of dsp, but I dont know how to solve the problem. And I dont know why the codec build ".ov5T", while the codec exactly runs on the  DSP. 

Here is the questions.

1. Why the codec needs build ".ov5T" and how the server integrates the ".ov5T" into the lib?

 

2. What changes should I make to use intrinsics without CCS?

 

Best Regards,

Yang
