In the execution of a computer program , a departure from the implicit or declared order in which instructions are being executed 在计算机程序执行中,正在执行的指令脱离隐含的或规定的指令执行顺序。
A computer register that has the capability of storing a word which can change an instruction before it is carried out by the computer 计算机的一种寄存器,它能存储一个字,这个字可以在一条指令执行前对它进行修改。
In the fourth chapter , the regulation of starting fault record prescribed by electric power ministry is introduced Dsp芯片是专用于数字处理的微处理器，具有极为快速的指令执行速度，良好的并行操作能力，强大的专用数字处理指令系统。
It is shown from fpga verification and computer simulation that the mcu core ' s maximum clock frequency and instruction efficiency are five times higher than those of mcs - 51 chips 验证结果表明，该mcu的最高时钟频率和指令执行效率等指标均优于mcs - 51的五倍以上。
Iu also deals with some execution units , such as comparator , alu , shifter , etc . meanwhile , iu is in charge of retiring instructions and accepting interrupts 它主要负责指令译码、指令发射、读取操作数、跳转预测检查、建立旁路、指令执行、指令退休和异常处理。
In programming , instructions which determine conditional jumps are often refer red to as control instruction , and the time sequence of execution of instruction s is called the flow of control 在程序设计中,确定条件转移的指令通常称作控制指令,而指令执行的时间序列叫控制流。
In this survey we explore the hardware aspects of reconfigurable computing machines , from single chip architecture to multichip systems , including internal structure and external coupling 在某一时刻一条指令执行过程中整个处理器的部件都服务于尽快完成这条指令，至少在概念上如此。
This paper presents the behavior description of alu and the execution of most instructions , and the explanation of them . then , presents the simulation waveforms and the synthesis result 文中给出了alu的行为描述和主要指令执行的描述，并做了相应解释，最后给出了仿真波形和综合结果。
Because with ia - 64 , the whole premise is to basically simplify the chip as much as possible in terms of the issue logic and the instruction execution , and to put more emphasis on the compiler 因为，对于ia - 64 ，整个前提就是在发送逻辑和指令执行方面从根本上尽可能地简化芯片，而将更多的注意力放在编译器上。
Many embedded applications have little or no need for floating - point arithmetic , and software emulation of powerpc floating - point instruction execution is usually more than adequate when it is needed 很多嵌入式应用程序很少或者根本不需要浮点算法，而当需要的时候，对powerpc浮点指令执行进行软件仿真就足够了。
