程序可以被编码为位模式并存储在主存储器中。然后，CPU可以从中提取指令并执行它们。反过来，要执行的程序可以容易地改变。
A program can be encoded as bit patterns and stored in main memory. From there, the CPU can then extract the instructions and execute them. In turn, the program to be executed can be altered easily.
记住，lqd指令只能从16字节边界加载，所以它会在加载期间忽略最低有效的四位，而只会从内存加载已对齐的四字。
Remember, the LQD instruction only loads from 16-byte boundaries. It will therefore ignore the four least significant bits during the load, and just load an aligned quadword from memory.

In 2006, the same research group reported that one of the 23 "vegetative" patients showed on imaging tests that her brain was responding to commands.
在两种模式下，设定64位寄存器的指令将影响所有64位。
In both modes, instructions that set a 64-bit register affect all 64 bits.
如果操作数的大小未在指令中指定，这就意味着操作数的大小并不十分重要(例如逻辑指令)或者它的大小为32位。
If the size of the operand is not specified in the instruction, that means either that the size doesn't matter (as in logical instructions, for instance) or that it is using a 32-bit value size.
另外，当 spu_add 被传递两个vectorunsignedint作为参数时，就会生成一条 a（32 位加法）指令。
For addition, spu_add, when given two vector unsigned ints as parameters, will generate the a (32-bit add) instruction.

The bug only seems to affect version 5.2 and 5.3 of the language, and only when they are run on Intel 32-bit CPUs that use the x87 instruction set.
虽然指令集主要是将它们拆解成4个32位的字，不过对于这种情况的处理已经有足够的支持了。
The instruction set is primarily geared around dividing it into four 32-bit words, but there is enough support to handle any of these situations.
主处理器是一个16 位的航空电子类处理器，它包含两个执行锁步 (lock-step)中指令的内部CPU。
The main processor was a 16-bit avionics-class processor that incorporated two internal CPUs that executed instructions in lock-step.

As the only known survivors of Order 66, it was up to Yoda and Kenobi to put a stop to the Sith.
指令计算整数值的按位求补并将结果推送到堆栈上。
Instruction computes the bitwise complement of an integer value and pushes the result onto the stack.
一个八位的指令寄存器也只能确定256种不同的操作以及对于这些操作的修改。
An 8-bit instruction register can only specify 256 different operations and variations on operations.
我之前从来没有这么热切与完整地想要遵从指令，并因此而如此之快地相信一位相对来说还算陌生的人。
Never before had I followed instructions so keenly and completely, or for that matter trusted a relative stranger so quickly.

Simulator is designed for two pilots (instructor and a beginner) and two passengers.
译码单元由指令缓存器和指令译码器构成，针对12位的指令代码翻译成16位控制信号，传送给处理器内部各个部件，用以保证各部件正常工作。
The encoding unit, composed of instruction buffer and command encoder, translates the 12-bit command code to 16-bit control signal, and ensures each part of the system to work steadily.
与使用32 位的寄存器相比，由于使用了 64位的寄存器，要执行相应的计算工作，只需使用更少的指令。
These can, by virtue of 64-bit registers, perform computations with fewer instructions than with 32-bit registers.
这条指令本身是基于位的，因此所有类型都使用相同的底层指令。
The instruction itself is bit-based, so all types use the same underlying instruction.
指令的其他位包含其他指令格式的一个或多个字段。
The remaining bits of the instruction contain one or more fields for the different instruction formats.
为了解决这一问题，乘法指令只使用每个32位的最低有效的16 位以便结果能够放进整个 32 位寄存器内。
To combat the problem, multiplication instructions only use the least-significant 16 bits of every 32-bit value so that the result will fit in the full 32-bit register.
