Abstract: An apparatus, a processor, a computer system and a method may be used to directly transfer and translate data between a memory format in an integer processing unit and a floating point format in a floating point processing unit. Data is stored in integer registers of the integer processing unit in a memory format and is stored in floating point registers of the floating point processing unit in a floating point format. A direct data link is provided between the integer register file of the integer processing unit and the floating point register file of the floating point processing unit. The direct data link includes a logic circuit which translates data between the memory format and the floating point format.

Abstract translation: 可以使用装置，处理器，计算机系统和方法在浮点处理单元中的整数处理单元中的存储器格式和浮点格式之间直接传送和转换数据。 数据以存储格式存储在整数处理单元的整数寄存器中，并以浮点格式存储在浮点处理单元的浮点寄存器中。 在整数处理单元的整数寄存器文件和浮点处理单元的浮点寄存器文件之间提供直接数据链接。 直接数据链路包括在存储器格式和浮点格式之间转换数据的逻辑电路。

Abstract: An emulating agent and method is provided that receives numbers having si, exponents and significands of varying lengths and possibly configured in a variety of incompatible formats and to reformat the numbers into a standard uniform format for uniform arithmetic computations in processors operating with different architectures. In one embodiment, the emulating agent has a three-field superset register configured to receive the sign of a number in a first field, the exponent of a number in a second field and the significand of a number in a third field, regardless of the original format of the number, resulting in a number represented in a standard uniform format for computation. The embodiment also allows high level access to the fields to allow users to control the size of the numbers inserted into the fields.

Abstract translation: 提供了一种仿真代理和方法，其接收具有不同长度的符号，指数和有效值的数字，并且可能以各种不兼容的格式配置，并且将数字重新格式化为用于使用不同架构的处理器中的统一算术计算的标准统一格式。 在一个实施例中，仿真代理具有三场超集合寄存器，其被配置为接收第一字段中的数字的符号，第二字段中的数字的指数和第三字段中的数字的有效数，而不管 原始格式的数字，导致以标准统一格式表示的数字进行计算。 该实施例还允许对字段的高级访问以允许用户控制插入到字段中的数字的大小。
