• 8097bh can do well in data collecting and dealing with high speed . the cpu is 16 - bit wide , and can operate by bit byte word and double word . there are many i / o function components in 8097bh and make the system designing very convenient
  8097bh是一种特别适合于数据采集与处理的微控制器，其cpu为16位，支持位、字节、字、双字的操作，片内带有多种可编程i o功能部件，方便了i o设计工作。
• 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。
