OpenVG Performance

Hello folks,

I've been playing around with the gpu-sdk1008 from Freescale. I am running the 2.6.35 kernel from the 11.09 BSP for the I.mx53. I am running the samples using the framebuffer (no X11).

The OpenGL ES1 and ES2 samples run beutifully with >= 100fps. The pinball example running from the Ubuntu image seemed to run equally well, although I dont have the FPS numbers from that.

However, when I run the OpenVG samples, they only give me 20-25 fps. Putting in some simple time measurements, it seems that PS_render takes ~45-50mS to render the tiger image for each frame. Also, if I run the OpenVG pageflip demo, it performs even worse at around 11 FPS.

Anybody have any clue as to where the problem may be? Should I just avoid using OpenVG?

Thanks for any help,

Mark

There is nothing wrong in the test or the way you are running. The performance number seems to be correct for the openVG tiger demo.

I would like to use the tiger demo code as a reference for my OpenVG development. So is the source code available somewhere?

Thanks.

Charles

Dear Charles Ung you can use of "gpu_sdk_v1.00".It contains OpenVG and OpenGL examples.
