| Abstract(in English) | We propose a multiplier with concurrent error detection, which can detect the error more than the designated numerical value. The multiplier has two multipliers, original one and partial duplicated one for checking. These outputs are compared for error detection. The partial duplicated multiplier calculates only most significant bits in product and has small area overhead. The proposed structure is suitable for floating point multiplication whose significand's msb is always one, because the proposed multiplier detects worse error. Thus, we show single precision floating point multiplication as an application, and evaluated it. As a result, area overhead is 52% of the original circuit when it compares only 16 bits on significand's 24 bits. This is half area overhead of duplication multiplier's one. |
