: I cross compile nano-X to arm arch. now it can run on cirrus logical 7500
chip(the OS is arm linux) , but it was slowly to refresh the screen. and the
color is uglily. so what is the lowest cpu requiement, should  I use SA1100? and
what is the default nano-X color setting ?

Use the SA1100, there's a version that runs at 206Mz.

The default color setting for Nano-X is whatever you
link in with the src/engine/devpal{1,2,4,8}.c files,
and then what the framebuffer is set to.

If you don't like the colors, you might want to change
the palettes.  On the other hand, I suspect your kernel
probably doesn't support the set palette ioctls.  Check
src/drivers/scr_fb.c for details.
