PURPOSE:To shorten an overall machine cycle and to improve the operation speed by separating the rounding processing and the overflow processing from an operating part and including them in a memory part. CONSTITUTION:A operation processing part consists of an addition cycle 1, and the overflow processing or the rounding processing is included in a memory cycle 2. For the purpose of operating a 29-bit adding part within 100nsec in an adding circuit having about 35nsec write time, the rounding processing and the overflow processing are separated from the adding part and are included in the cycle of the memory. Thus, the time of both the addition cycle and the memory cycle are equalized approximately to shorten the overall machine cycle, and the operation speed is improved. |
