摘要

在经典欧几里得算法的基础上，建立了对有理数进行加、减、乘、除运算的算术单元基础。该单元使用一个统一的算法进行所有操作，包括四舍五入。本文描述了一种基于SRT部门已知技术的二进制实现。最后，分析了使用无纹波、免进位加法的硬件实现，并使其适应于有理数的浮点斜杠表示。

An integrated rational arithmetic unit

Based on the classical Euclidian Algorithm, we develop the foundations of an arithmetic unit performing Add, Subtract, Multiply and Divide on rational operands. The unit uses one unified algorithm for all operations, including rounding. A binary implementation, based on techniques known from the SRT division, is described. Finally, a hardware implementation using ripple-free, carry-save addition is analyzed, and adapted to a floating-slash representation of the rational operands.
