SGX530 3D Graphics Engine in DM8148 problem

Hello All,

I have a question about limitations of the texture size the SGX530 core is able to handle in DM8148.

Question: The SGX530 core on a max texture size that is 2k x 2k? Our max resolution will be 720*480(rgba), so it can load our texture successfully?

If resolution is ok, then frame rate can render 30 fps?

    My algorithm need 720x480 texture size, and 30 fps process speed.(algorithm only do lookup table).

    I can't find the texture loading timing that will influence the performance.

    I will measure the loading texture time, but meet another problem.
    My c code use the glTexImage2D() to load texture, but the dimensions must be power of 2, so I do some experiments.
    ex1. load texture size 1024x512, it is work.
    ex2. load texture size 720x480, it is failure.
    So I find another function gluBuild2DMipmaps() to replace, but I can't find it's header file, so I guess it's possible that SGC530 no implement this function ?
