摘要： A computing system comprising capable of handling floating point operations during program code conversion is described, comprising a processor including a floating point unit and an integer unit. The computing system further comprises a translator unit arranged to receive subject code instructions including at least one instruction relating to a floating point operation and in response to generate corresponding target code for execution on said processor. To handle floating point operations a floating point status unit and a floating point control unit are provided within the translator. These units are cause the translator unit to generate either: target code for performing the floating point operations directly on the floating point unit; or target code for performing the floating point operations indirectly, for example using a combination of the integer unit and the floating point unit. In this way the efficiency of the computing system is improved.
摘要翻译：描述了包括能够在程序代码转换期间处理浮点运算的计算系统，包括包括浮点单元和整数单元的处理器。所述计算系统还包括翻译单元，其被配置为接收包含与浮点运算有关的至少一个指令的主题代码指令，并且响应于生成用于在所述处理器上执行的相应目标代码。为了处理浮点运算，翻译器中提供了一个浮点状态单元和一个浮点控制单元。这些单元使翻译单元产生：用于直接在浮点单元上执行浮点运算的目标代码; 或用于间接执行浮点运算的目标代码，例如使用整数单元和浮点单元的组合。以这种方式，提高了计算系统的效率。
