doubleword meaning in English
双字组
Examples
- Byte , halfword , word , and doubleword sizes
字节、半字、字和双字大小。 - Load doubleword and reserve indexed
(加载双字并预留变址) - Store doubleword conditional index
(存储双字条件变址) - 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。 - Powerpc , powerpc as , and the early ibm powerpc 4xx family are primarily big - endian machines , meaning that for halfword , word , and doubleword accesses , the most - significant byte is at the lowest address
Powerpc 、 powerpc as以及早期的ibm powerpc 4xx家族大部分是字节排列顺序最高位在最前的机器,这就意味着对半字、字以及双字访问来说,最重要的字节( most - significant byte , msb )位于最低的地址。
