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。
