This project is considered to be a complementary tool for publishing research results in the area of reversible logic (definitions) synthesis. In the limited space of any standard publication, only the gate count and cost calculation are usually shown, whereas the actual designs would be of more interest. Some authors may use nonstandard gates, other authors may use their own metric for the calculation of the circuit cost, which further complicates the comparison of circuits. Here, a unified approach for comparison of the results is suggested, where any author can publish their circuit and/or compare it with the already posted ones. In order to unify the different gate libraries and cost metrics the following restrictions apply. First, all circuits must be strings of gates, i.e., no fanout or feedback allowed. Second, the gate libraries are limited to:
Input constants may take the values of either 0 or 1. Finally, the resulting cost is measured with three numbers: garbage, number of gates, and quantum cost. The results are published in two formats: machinereadable format and a picture with optional author comments. Everyone is welcome to submit their results in the machinereadable format for the immediate publication on this website as long as no better design is already published.
Circuits for the following benchmark functions are currently available:
