Abstract

IEEE-754 2008 has extended the standard with decimal floating-point arithmetic. Human-centric applications, like financial and commercial, depend on decimal arithmetic since the results must match exactly those obtained by human calculations without being subject to errors caused by decimal to binary conversions. Decimal multiplication is a fundamental operation utilized in many algorithms, and it is referred in the standard IEEE-754 2008. Decimal multiplication has an inherent difficulty associated with the representation of decimal numbers using a binary number system. Both bit and digit carries, as well as invalid results, must be considered in decimal multiplication in order to produce the correct result. This chapter focuses on algorithms for hardware implementation of decimal multiplication. Both decimal fixed-point and floating-point multiplication are described, including iterative and parallel solutions.
十进制硬件乘法器
IEEE-754 2008扩展了十进制浮点运算标准。以人为中心的应用程序(如金融和商业)依赖于十进制算术,因为结果必须与由人类计算获得的结果完全匹配,而不会受到由十进制到二进制转换引起的错误的影响。十进制乘法是许多算法中使用的基本运算,它在标准IEEE-754 2008中被引用。十进制乘法与使用二进制数系统表示十进制数有一个固有的困难。为了产生正确的结果,在十进制乘法中必须考虑位进位和数位进位以及无效结果。本章重点介绍十进制乘法的硬件实现算法。描述了十进制定点乘法和浮点乘法,包括迭代解和并行解。
