| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A floating-point multiplier with reduced precision error detection is proposed. It uses a truncated multiplier for checking of mantissa multiplication instead of duplication. The truncated multiplier in it is designed considering rounding in floating-point operation, and it can detect any erroneous value with error larger than one unit in the last place (ulp). The circuit area of it is smaller than that of duplicated one. Hardware overhead of a single-precision multiplier is about 75% and that of a double-precision one is about 65%. |
