DirectGraphics.getNativePixelformat() returns 4444£¬there are 4 bits for alpha value. Is this means 7650 hardware support alpha blending, or it is implemented by java VM code?

Yes it does support alpha blending but remember only 16 levels (4 bits) of it so 0-15 maps to one transparency level and 16-31 maps to another and so on..
