Based on the decrease-radix design presented previously, a TOC can satisfy either a user requiring huge capacity for data calculations or one with a moderate amount of data, if it is equipped with a prepared adder. Furthermore, with the application of pipelined operations and the proposed data editing technique, the e?ciency of the prepared adder can be greatly improved, so that each calculated result can be obtained almost within one clock cycle. It is hopeful that by employing a MSD adder, users will be able to enter a new dimension with the creation of a new multiplier, new divider, as well as new matrix operator in a TOC in the near future. 关键词：光计算机加法器 MSD 三元施工原理用户需要流水线作业
