Not 4 And4 Or4 Xor4 Add4C Register8 This has one input bus, in, and one output bus, out. Each bit of the output is the inverse (i.e. not) of the corresponding input bit. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of logically anding together the corresponding input bits in a and b. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of logically oring together the corresponding input bits in a and b. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of logically Xoring together the corresponding input bits in a and b. This has two input buses, a and b, and one output bus, out. Each bit of the output is the result of adding together the corresponding input bits in a and b, while making sure that any carry is propagated to the next bit. Add4 also has an additional carryIn input, which is used to feed carry into first addition, and a carryOut output which carries the carry out of the final addition. This gate has one 8-bit input bus, in, and one output bus, out, and is designed to store a single byte (8-bits) of information. As with pre-supplied Bit, a further input load controls whether the output should be updated to reflect the new input value (when true), or should preserve the output.

Gate Mux4 Description This has two input buses, a and b and one output bus, out. Also present is a sel input, which is used to select whether input a or b is passed to out. If sel is false, input a should be selected, otherwise input b should be selected.
