If you vectorize this code, since you are treating the values as bytes, that means that each instruction will operate on 16 values at once!
如果对代码进行向量化,由于您正在将这些值当作字节进行处理,这意味着每条指令都要一次操作16 个值!
Underlying the front-end parsers is a symbolic instruction set – a kind of portable assembly code – which can be translated to any of the supported machine architectures.

Iters left No, it is not. Therefore, skip the rest of that block of code - and go to the next instruction, which is, y ah, print out y.
是不是大于0?,Is,iters,left’s,value,greater,than,zero?,不,这回不是了,因此,跳过这块代码,而去执行下一个指令,也就是,显示。
Each instruction on the PowerPC is exactly 32 bits long, with the instruction's opcode (the code telling the processor which instruction it is) taking the first six bits.
PowerPC上的每条指令都正好是32位长,指令的opcode(操作符,告诉处理器这条指令是什么的代码)占据了前6位。
Ruby - with the exception of the handful of lines of C code for the yield_debugger instruction.
比起那些依靠trace方式调试的Ruby实现(不论这些实现的速度有多快),全速调试器都使得Rubinius具有了独特的优势。 同样值得注意的是:除了整个yield_debugger指令使用了一些C代码,绝大多数Rubinius调试功能都是内建的。
You then combine the comparisons using the and instruction (note that you could have combined all the logical instructions into one with an xor, but the code would have been much less clear).
可以通过and指令进行组合比较(注意可以用一个xor将所有逻辑指令结合成一个,但那样做的代码应该比这个要清晰很多)。
If a number, it is sent to a remote computer which responds with an instruction that tells the phone to perform an action associated with that particular bar code.

You set some registers and issue a system call instruction (or an interrupt) and have the kernel code called directly from the trap handler.
你可以设置一些寄存器,并发出一个系统调用指令(或中断),并由陷阱处理程序直接调用内核代码。
If you don't have a compiler that can produce code to take advantage of the underlying processor architecture and instruction set, then the fastest machines will be useless.
如果您没有可以生成代码来利用底层处理器架构和指令集的编译器,那么最快的机器也将是无用的。
First, you shouldn't assume that the above assignment would be compiled as a single machine instruction unless you personally verify the machine code yourself.
首先,不应该假定上述赋值语句一定会被编译成一条机器指令,除非亲自验证了机器代码。
Because of the nature of memory systems and instruction-set designs, the best generic routine to copy memory is rarely as fast as code written to copy a particular length.
由于内存系统和指令集设计的特性,用于复制内存的最佳通用例程的执行速度通常比用于复制特定长度的代码慢。
An executable unit begins at the start of every basic block and at any instruction that corresponds to a line of source code that is different than the previous instruction.
一个可执行的单元由每一个基本快开始,而与每行源代码相对应的指南与前面版本中的指南有所不同。
Change these lines of code according to the parser instruction.
根据解析器操作说明更改这几行代码。
Note: to reference the lines of assembly code in the following explanation, I refer to the last two values of the instruction address because they all begin with 054d20.
注:为引用下列说明中的汇编代码行,我将引用指令地址的最后两个值,因为它们都以054d 20开头。
This requires changes to the OProfile kernel code to sample the SPU instruction Pointers regularly.
这需要修改oprofile的内核代码来周期性地对SPU指令指针进行采样。
To uncover the failed instruction in the code, do an object dump of the executable using objdump, which lists the instructions generated by the compiler.
要查看代码中是哪条指令出错了,可以使用objdump命令输出可执行文件的代码,该命令会列出编译器所生成的指令。
Instruction has the smallest possible instruction size enabling code patching with a break point and generating minimal disturbance to the surrounding code.
指令具有使通过断点修补代码成为可能并对环境代码的影响最小的可能的最小指令大小。
But Kemeny and Kurtz used what they learned to craft the Beginner's All-Purpose Symbolic Instruction Code, or Basic, starting in 1963.
但从1963年开始,Kemeny和Kurtz使用他们学会的东西精心编织初学者通用符号指令代码即Basic。
I developed the SSE2 code simply by adding an SSE2 instruction after each line of FP code.
在每一行FP代码之后,我简单的增加了一个SSE2指令。
The CFG generation process can also be attacked by obfuscating the assembly code such that one cannot determine the correct target of a jump instruction, such as using a jump through register.
攻击CFG生成进程也可以是通过混淆汇编代码以致它不能够正确地确定跳转指令的目标,比如使用寄存器指示跳转目标。
