dpu_1_g2d_basic_test#

Overview#

This is a test of the graphics performance of the Blit Engine hardware and the graphics enablement of the G2D (2D graphics) library.

g2d_basic_test.c uses the G2D API to send graphics operations to the Blit Engine. The engine does pixel processing and places its result in the destination buffer. The engine operations are timed and checked for correctness.
