sum of absolute difference computation using verilog for fpga

[yupina-chan]

hi. i need to compute the sum of absolute differences of image histogram from bins 0 to 255. this will be used for my image comparison. i have coded my own and simulation worked right but my problem is that after compilation, the total logic elements shown is 70% already and this is only for a 12x12 input image. my final input image is 640x480. can somebody help me with coding efficiently?

Nobody can help you with optimizing your code, if you don't post the code. Most of the people on this forum don't have crystal balls. ;-)
