Accelerating Performance of Qt on TI's Embedded Processors
summary
Texas Instruments shows concrete steps to speed up Qt on ARM SoCs: enable SGX-based OpenGL ES for 3D, add a NEON-backed raster engine yielding 2x–3x 2D speedup, and push audio/video to DSPs via a GStreamer DSP plugin so ARM is idle while hardware decodes. A C6xEasyRun tool converts hot C code to run on DSPs with no DSP coding and reports 30–35x Mandelbrot speedup. Accelerated Qt binaries and touchscreen demos (matrix launcher, FFT GUI, ultrasound) ship in the TI SDK.
