show me a code of adder

As an AI language model, I can provide you with a sample code of adder in different programming languages. Here are some examples:

Python:

def adder(x, y):
  return x + y

Java:

public static int adder(int x, int y) {
  return x + y;
}

C++:

int adder(int x, int y) {
  return x + y;
}

JavaScript:

function adder(x, y) {
  return x + y;
}

Feel free to modify the code according to your needs.

show me the code verilog example

以下是一个 Verilog 的例子：

module adder(input [7:] a, input [7:] b, output [8:] sum);
assign sum = a + b;
endmodule

这是一个简单的加法器，它将两个 8 位的二进制数相加，并将结果输出到一个 9 位的二进制数中。

Draw a schematic of NAND ROM with 8-word × 2-bit This ROM works as a lookup table to implement a full adder.

Here is a schematic of a NAND ROM with 8-word × 2-bit that works as a lookup table to implement a full adder:

        A1   A0
       ┌───┬───┬───┐
    D0 │ 0 │ 0 │ 1 │
       ├───┼───┼───┤
    D1 │ 0 │ 1 │ 0 │
       ├───┼───┼───┤
    D2 │ 0 │ 1 │ 1 │
       ├───┼───┼───┤
    D3 │ 1 │ 0 │ 0 │
       ├───┼───┼───┤
    D4 │ 1 │ 0 │ 1 │
       ├───┼───┼───┤
    D5 │ 1 │ 1 │ 0 │
       ├───┼───┼───┤
    D6 │ 1 │ 1 │ 1 │
       └───┴───┴───┘

This ROM has two address inputs, A1 and A0, and eight data outputs, D0 through D7. The data outputs represent the output of a full adder for each possible combination of the two input bits (A1 and A0). For example, if A1=0 and A0=1, the output of the full adder can be read from D2, which has a value of 011 (binary) or 3 (decimal). The other data outputs represent the output of the full adder for the other possible combinations of A1 and A0.
