This is not possible with a Von Neumann single-address bus architecture.

这是不可能的了冯诺伊曼单地址总线架构。

The disadvantage of the PRECHARGE command is that it requires that the command and address buses be available at the appropriate time to issue the command

使用预充电指令的缺陷在于，需要命令和地址总线在合适的时间处于可操控状态时，才能够发出预充电指令。

After input the reference signal, sine and cosine AC voltage proportional to shaft angle was formed.

采样后经A/D转换和时内部地址总线信号译码，控制轴角数字信号。

Big-Endian ConfigurationA signed byte load expects data on data bus inputs 31 through to 24 if the supplied address is on aword boundary, on data bus inputs 23 through to 16 if it is a word address plus one byte, and so on.

Uniprocessor designs have built-in bottlenecks.the address and data buses restrict data transfers to a one-at-a-time flow of traffic.the program counter forces instructions to be run in strict sequence.even if improvements in performance are achieved by means of faster processors and more instruction parallelism,operations are still run in strict sequence.however,in a uniprocessor,an increase in processor speed is not the total answer because other factors,such as the system bus and memory,come into play.

单处理器设计有内置的一些瓶颈。地址和数据总线限制数据传输的同时同地址的数据冲突情况。即使是通过更快的处理器和更多的并行指令，当然也包括维护，这些方式来提高的性能，程序的运行仍然被限制在严格的程式规则中。然而，在一个单处理器里，处理器速度的提高时不能完全解决这个问题的，这是因为像系统总线和存储器等其他因素同样在起作用。
