/255 is rather hard work

/256 is a lot easier as it is just a right bit shift by 8. In FPGA there is no need to do any bit shifting like this.

But at the same time I want data bus of the same width(before normalization and after normalization).

Further, Is it possible to re-gain the same image on de-normalization?
