Example text

Column (6) addresses the location within the bank. Column Number (8) Output: This is the bit that is output as a result of adding A, B, and the carry operation from the previous addition operation. Let us add 1 and 1 using the state diagram (Fig. 3). Assuming the initial state is 0, the addition of input bit A = 1 and B = 1 results in an input of 2 (in decimal), output of 0, and next state of 1. The next values of A and B are 0, so the next input is 0, output is 0 and next state is 2. Again A and B are 0, the input is 0, the output now is 1, and the next state is 3.

The state number is shown in column (7). Column Number (6) After Shift: This column shows the result of shifting column 5 right by one bit. This is the operation that would be performed to get ready to add the next two values of input bits A and B. The value is assigned a state number (column 7) that is the next state (column 1). Column Number (7) Next State: This number represents the value in column (6). It is the memory location that is used in the next decoding operation. The sum of input bits A and B select the memory bank to use.

A functional diagram of the state-machine adder, which can be implemented, is shown in Fig. 4 [4]. Data are input by storing two complex binary base numbers in the input memories. 15 Speed-up comparisons of adders’ designs [3] Minimum-delay adders Minterms Number of minterms giving different outputs (M) Number of minterms giving same outputs (m) Time taken to compute all M-terms (2:1) Time taken to compute all m-terms (1:1) Total time taken to compute all M + m-terms Average time for adding two nibble-size operands Speed-up Base (-1 ?
