Table 3 Performance indexes the divider and its modules with \(n \ge 3\)
From: Designs of the divider and special multiplier optimizing T and CNOT gates
Operations | T-count | T-depth | CNOT-count | CNOT-depth | H-count | S-count | X-count | Width |
|---|---|---|---|---|---|---|---|---|
FMD | 4n | n + 1 | 7n − 2 | 3n + 2 | 2n | 2n | 3 | 2n + 1 |
IMD | 8n − 1 | 2n + 1 | 11n − 3 | 4n + 4 | 4n − 2 | 0 | 0 | 2n + 2 |
LMD | 20n − 8 | 5n | 26n − 14 | 14n − 4 | 8n − 4 | 0 | 0 | 2n + 2 |
