Abstract(in English) | Reconfigurable logic devices are classified into the fine-grained approach and the coarse-grained approach by the granularity of its basic logic cell. Since there are suitable and unsuitable operations for these devices, it is difficult to always balance between the operation speed and the area efficiency in a application. To solve this problem, we propose a new logic cell architecture that based 4-bit ripple carry adder with configuration memory. It becomes possible to realize two features which are high-speed in coarse-grained cell and versatility in fine-grained cell. In this paper, we evaluated our logic cell by using the logic synthesis library. As a result, we found that our proposed cell has enough the area efficiency by its gate structure. Moreover, the number of configuration memory bits was reduced by about 15% than 4-LUT in arithmetic operations. |
