Hi! I am doing a laboration tomorrow and I would love it if someone could explain how this system works.
I know exactly how a system with 4 x 1-bit ALU's work, but I'm not sure of what's happening in this system.
This is the 4-Bit ALU system with 4 D-FlipFlops that stores the numbers until you press the clock on the Nios II board.
I thought that every 1-bit ALU needs it A and B values to be able to either give a carry or not to the next one. On this system, it seems like the a-values are only given AFTER the B values have already been stored in the Flipflops... I'm so confused about this.
Could someone please explain to me how this system works?
