浮点指令 meaning in Chinese

floating point i truction
floating point instruction

Of course , doubleword integer instructions are not available on 32 - bit implementations , and floating - point instructions are supported only through software emulation on most embedded implementations
当然，在32位的实现上还不能用双字整数指令，在大部分嵌入式实现中浮点指令也只是通过软件仿真提供支持。
Many embedded applications have little or no need for floating - point arithmetic , and software emulation of powerpc floating - point instruction execution is usually more than adequate when it is needed
很多嵌入式应用程序很少或者根本不需要浮点算法，而当需要的时候，对powerpc浮点指令执行进行软件仿真就足够了。
