Just put down the design for a simple 4 bit sliced ALU that I might implement for my DIWhy mini computer, created with the logic simulator program Digital, which is an easier to use LogiSim like program.
Possible operations are, Not A, A and B, A or B, A xor B, A + B, A + 1, A - B and A - 1, as well as checks for A == B and if Out == 0.
It also got its name, DWMC-16, for DIWhy MiniComputer 16-bit.
