地址总线

The system bus is divided into three logical functions; the address bus, the data bus and the control bus .

系统总线的功能在逻辑上被划分为三部分：地址总线、数据总线和控制总线。

Memory is by memory address decoder, literacy control circuit, the address bus and the data bus.

存储器是由存储体、地址译码器、读写控制电路、地址总线和数据总线组成。

A memory address consists of binary data being output on an appropriate bus which we call the address bus.

一个存储器地址是由输出到适宜的总线上的二进制数据所组成。这个总线我们称为地址总线。

Address bit 0 of the external address bus when the external data bus is configured for an 8 bit width.

地址位外部地址总线0时的外部数据总线宽度为8位配置。

Contents of a memory location or register within a particular peripheral, ints on the data bus.

设中的存储器地址或寄存器中的内容时，处理器设置地址总线并在数据总线上接收

When the processor wants to read the contents of a memory location or register within a particular peripheral, it sets the address bus

当一个处理器想去写某一特定外设中的存储器地址或寄存器中的内容时，处理器设置地址总线并在数据总线上接收内容。

The circuit comprises a comparison circuit, a negation gate and a first coincidence gate, wherein the comparison circuit is used to output read screen signals of a storage unit corresponding with bus signals of a second port address, the negation gate is used to inverse the read screen signals of the storage unit which are corresponding with the bus signals of the second port address, one input end of the first coincidence gate receives the read screen signals of the storage unit which are corresponding with the bus signals of the second port address after being inversed, the other input end of the first coincidence gate receives the read enable signals of a second port, and the output end of the first coincidence gate is connected with the read enable end of the second port.

所述电路包括：比较电路，用于输出第二端口地址总线信号对应的存储单元读屏蔽信号；非门，用于对第二端口地址总线信号对应的存储单元读屏蔽信号进行非运算；第一与门，第一与门的一路输入端接收非运算后的第二端口地址总线信号对应的存储单元读屏蔽信号，第一与门的另一路输入端接收第二端口的读使能信号，第一与门的输出端连接第二端口的读使能端。

This method reorders the ten least significant bits of offset address according to the value of offset address, and the optimal sorting pattern is transmitted through the high bits of bus without the need for redundant bus lines.

该编码方法根据偏移地址的值域对地址总线的低位进行优化重排，通过高位地址总线传送排序矢量至存储器的地址接收端，相对于传统的地址总线编码方法，具有更低的总线跳变率。

The address is transmitted to the memory through a set of parallel wires called an address bus. A 16-bit address bus can locate 64K(2^16) or 65536 memory locations. A 32-bit address bus can locate 4 Gigas(2^32) of different memory locations.

向存储器传送地址是经过一组为地址总线的并行导线进行的。16位地址总线可以确定64K （2的16次幂）即65536个存储位置。32位地址总线可以确定4G （2的32次幂）个不同的存储位置。

The data location includes memory data memorizer and memory map register, which share uniform data and address buses, at the same time occupy independent physical spaces, respectively, both physical and logic addresses separated and independently addressed, respectively, and can multiplex the same logic address.

内存数据存储器和内存映射寄存器共享统一的数据总线和数据地址总线。同时，内存数据存储器和内存映射寄存器各自占有独立的物理空间，物理地址和逻辑地址均分开，各自独立编址，内存数据存储器和内存映射寄存器对同一逻辑地址可以复用。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"
