第一个操作数是目标寄存器，第二个操作数是要加载的D -Form地址。
"The first operand is the destination register and the second is the D-Form address to load."
这是因为调用或跳转语句的机器码操作数是相对地址。
This is because a call or jump statement's machine code operand is a relative address.
如果累加器内容是负数，分支到操作数指定的地址。
JPN Branch to the address specified by the operand if the contents of the accumulator are negative.
该算法易于用硬件实现，其操作数访问地址的产生速度快于已有的算法。
The data and twiddle factor address generation hardware is shown to have higher speed than previous methods.
操作数可以是一个MMX技术注册或一个内存地址。
The operand is either an MMX technology register or a memory address.
操作数可以是一个128位的XMM寄存器或内存地址。
The operand is either a 128-bit XMM register or a memory address.
这些指令的特点是我们必须定义alu操作数和ALE(地址锁存允许)运算，除了两个例外：乘法和除法。
Main characteristic of these instructions is that we have to define both ALU operands and ALE operation. Exceptions among these instructions are mul (multiply) instruction div (divide) instruction.
从分析存储器操作数的存放地址入手，可以更好地理解寻址方式，准确访问存储器操作数。
We can understand the addressing mode better and call it correctly by analyzing the storing position of memory's data operation.
即每一个存储在内部存储器上的操作数都有唯一确定的地址(物理地址)，这个地址由两部分构成：段地址和段内偏移地址。
It is to say that each operating data stored in internal memory has its only exact address (physical address), composed of two parts: segment address and effective address.
在磁盘阵列中，为了提高I/O性能，减少I/O执行时间，采取了将分解到同一磁盘上同命令类型且操作数据地址相邻的多I/O命令合并的策略。
In order to improve I/O performance and reduce I/O implementation time, a kind of command combination strategy is used.
