摘要: |
大型机采用的软硬结合的迭代除法方案具有很高的计算速度,但存在精度合理性问题。经过大量随机数试算验证和算法的误差分析证明:本文中提供的优选除法方案,提高了除法精度,解决了精度合理性问题。该除法方案装机运行后,提高了大型机的适应能力和运算速度,改善了处理效果。 |

Abstract: |
Iterative division schemes using hardware-software are studied in this paper. The accuracy control method is suggested for the x/x≡1. The division schemes are used for the supercomputer. |
Keywords: interation,diviser,optimum seeking method,accuracy reasonableness,hardware-software |
