If the page fault is due to an instruction fetch ( meaning the process was trying to load an instruction from the page to execute), the kernel marks the file as computational. 如果是由于指令取出而导致的缺页(意味着该进程正在尝试加载来自该分页的指令,以便进行相关操作),那么内核会将该文件标记为计算性的。
If the first instruction in this fetch group is an even pipeline instruction and the second one is an odd pipeline instruction, they can both be issued simultaneously. 如果这个取出组中的第一条指令是一条even流水线指令,第二条指令是一条odd流水线指令,则它们都可以同时执行。
After every instruction fetch, if we increment this address, it will accurately point to the next instruction in the sequence. 在每次取指令后,如果我们使地址增量,那么就会准确地指向指令代码序列中的下一条指令。
At per cycle, processor fetch many instruction from many thread to manage operation. 在每个周期,处理机从多个线程取出多条指令调度执行。
Based on the ( program counter) PC arbitrage strategy of multi-path execution, designing fetch instruction unit suit for selective dual path execution. 通过研究多路径执行中的PC仲裁机制,设计适合双路径执行结构的取指部件。

An instruction buffer based on the stated FIFO is applied in an embedded Java processor, and such design proved to be effective for enhancing the efficiency of the instruction fetch operation while the Java byte code verifies in real time, and for facilitating the instruction folding operation. 该设计在一种针对嵌入式系统的Java虚拟机的硬件实现中得到应用,提高了Java处理的取指效率,并对随后的指令折叠提供了方便。
The key of this design is the design of instructions state machine. Every instruction cycle includes 8 machine clock cycles, is made up of fetch instruction, decoder instruction, execute instruction, writing RAM, writing register and reading RAM etc. 本设计的关键点为指令执行状态级的设计,每个指令周期包括8个机器时钟周期,由取指、译指、执指、RAM读、寄存器写、RAM写等组成;
In this paper, the authors propose an effective instruction fetch control mechanism for SMT processors through combining a value based branch predictor and an instruction throughput based fetch policy. 通过将一个基于值的分支预测器和一个基于线程推进速度的取指策略相结合,提出一种新的取指控制机制。
