Thanks for the update @pborcin ! Could you please sum-up a procedure for testing?

I'd like to see what performance increase can we get with this new implementation compared to the old (ANSI C) implementation.

You can find the testing framework in components/esp_lvgl_port/test_apps/simd, from there idf.py set-target esp32s3 build. Once flashed you can select the number of the test you want to run (rgb565 benchmark test is currently number 4). You can change the matrix size in components/esp_lvgl_port/test_apps/simd/main/test_lv_fill_benchmark.c in the associated TEST_CASE.
